Michaelis–Menten kinetics Essays

Have you ever wondered what living objects were made up off? How food is digested? No not by cells, but those catalysts that break down substances. They are called enzymes. Enzymes are biological molecules, proteins, which act as catalysts and help complicated reactions occur everywhere in life. Enzymes are very precise catalysts that usually work to complete one assignment. Example being; an enzyme that helps digest proteins will not be useful to break down carbohydrates. Also, you will not find

A boiling point of a substance is dependent on the temperature at which the substance can change its matter, such as liquid to gas. The molecules present in liquid are tightly compressed together, though they are still moving and colliding. If the liquid is heated, there is a rise in temperature which generates vibrations throughout the liquid, resulting in more collisions between molecules (Helmenstine, 2017). Once the collisions between the molecules become quite intense and rapid, boiling starts

OH (1) It is necessary to determine the reaction kinetics for the reaction in Equation 1. Reaction kinetics is an unavoidable stepping stone needed for reactor design and optimising these reactors to their full potential. It is a measurement of how quickly a reaction occurs. The rate of a reaction is directly proportional to the reactant concentrations and the temperature of the reactor. (Schaller) The problem at hand is that the reaction kinetics is not known and need to be determined to understand

Lab report: How does the surface area affect the rate of reaction ? Introduction The rate of a chemical reaction (or reaction rate) is a calculation of the total time needed for a reaction to take place, or how quickly the reactants are transferred into products in a chemical process. This rate can be measured in two methods. The first one is to measure the rate at which the reactants are used up per unit of time, while the second method is to measure the rate at which the products are formed

Shock waves and its effect on supersonic flight Definition of shock wave – shock waves are defined as a compressional large amplitude wave evolved by abrupt change of pressure and density in a narrow region travelling through a medium, especially in air, caused by earthquake/explosion or by an object moving faster than the speed of sound. The thickness of the shocks is comparable to the mean free path of the gas molecules in the flow field. Formation – the flow consists of a large number of fluid

4.3.8 When a ball is pitched, it stay in motion until it either fall, or is acted on by another object such as the bat, or caught by a person. The pitch and speed depends on the mass of the ball. Although it should be the same size, practicing with different balls will affect the speed. During the process of pitching, this will have a reaction on the ball causing it to move from one point to another. 4.3.9 ANGULAR MOMENTUM = MOMENT OF INERTIA X ANGULAR VELOCITY The angular velocity is the axis,

experiment. Despite the fact that the masses were equal, when the two pucks collided there was sound energy given off as well as minor amounts of heat energy, this is the most likely reason for the momentum not being conserved, . The percent change in Kinetic Energy was also calculated using the

How Roller Coasters Convert Potential Energy to Kinetic Energy Maximus Rosales Grade 11 Potential Energy was proposed in the 19th century and can be shown in many ways during a roller coaster. When Potential Energy was proposed in the 19th century it was proposed by a Scottish engineer and physicist whose name was William Rankine, who studied mathematics and physics. Potential Energy is when an object contains energy because of the position of the object. Therefore, a roller coaster shows

Physics Project For my Physics Project I decided to learn about the physics behind cradling a Lacrosse ball. I also wanted to see what happened when I changed the size, shape, and weight of what I was cradling and how that would affect the result of the level of difficulty and my level of performance. My hypothesis was that cradling objects that were the same size but lighter than a lacrosse ball would make it the easiest to learn how to cradle and improve my performance the most efficiently

and test a model car and to identify the different forms of energy converted in the model car. The different forms of energy contained in the model car are, kinetic energy, gravitational potential energy, and also heat energy. Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles. Kinetic energy is contained in the model car is because the model car is processed by a moving object. The speed and the mass of the model

we used Gravitational potential energy, Kinetic energy, Momentum, mechanical energy, and elastic potential energy (among other things) to make this experiment happen. Our experiment started out with a type writer’s tab bar being pushed to push a car down a ramp, the typewriter has potential energy before the key is pushed as does the car. When the tab bar is pushed the typewriter, then has applied force which will change the energy from potential to kinetic energy. The transfer of energy from the

TASK: When a ball is dropped from a height, it loses some of its energy and each bounce gets shorter. Your investigation will determine the effect of original drop height on bounce height. From this, energy loss can be calculated between bounces. As different groups will be using different balls, you will be able to compare energy loss with different balls. You are required to present your findings in a lab report format, which has been detailed below. The lab report must be typed. The task

aim of this investigation was to experimentally determine the order and rate law expression of the reaction between sodium iodide and iron (III) nitrate 9-hydrate. Introduction The most interesting topic in grade twelve chemistry was the unit on kinetics, therefore after brainstorming a mind map on the stimulus that I chose, I was interested in creating an experiment to determine the order and rate law expression between two reactions myself. The original idea for this project came from a lesson

energy level? The healthier the food you eat the more energy you will get from it. After you’ve consumed the food, it is stored as potential energy for your body. That energy will then be converted into kinetic energy when you begin a physical activity. In this paper, potential and kinetic energy will be discussed, along with the factors that affect them, and how they are converted. POTENTIAL ENERGY “Potential energy is energy which results from position or configuration” (Georgia State University

fall, the momentum of this object builds up potential energy as the arm rotates around the fulcrum. Then, Newton’s Third law as the counterweight falls, the sling (on the other end of the beam) rotates up, then the potential energy is turned into kinetic energy as the projectile is released from the sling and

Conservation of Momentum: If objects within a system collide, the momentum of the individual objects before and after a collision may change, but the total momentum of the system will remain constant. 1. Describe what happened to the top ball during the double-ball drop experiment. During the double-ball drop experiment, the top ball moved up while the bottom ball moved down. During the initial drop, the balls are released and fall to the ground with the same acceleration. However, the instant

The graph for the lab of ln k versus 1/T displays a line of best fit with a negative slope and an R^2 value of 0.9544, showing that the line fits reasonably well with the data provided. This negative trend shows that as 1/T increases, the value of the natural log of the reaction constant will decrease. This linear trend and the equation that was created for it of y=-4687.6x + 24.181 is what is expected due to its relationship with the Arrhenius equation ln⁡k=-E_a/R (1/T)+ln⁡A. The Arrhenius equation

bounce higher than if it was from a lower height. This is because as the ball is falling it is picking up speed which gives it more kinetic energy. When the ball hits the ground its kinetic energy is turned into elastic energy this makes the ball flatten out. Then that elastic energy is converted right back into kinetic energy when it goes up. So the more kinetic energy a ball gets when it is dropped the more energy it will have when it hits the ground which will give it more energy when it is

The topic of research is, “how fast does an Alka-Seltzer tablet make gas?”. In the experiment, the scientists will be measuring the chemical reaction rates that occur, when 1 Alka-Seltzer tablet is placed in a specific temperature of water. The independent variable during the experiment will be the temperature of the water (degrees Celsius). The dependent variable during the experiment will be, the rate in which gas is produced (in seconds). The constants of the experiment, will be the amount of

Abstract In this experiment, the reaction kinetics of the hydrolysis of t-butyl chloride, (CH3)3CCl, was studied. The experiment was to determine the rate constant of the reaction, as well as the effects of solvent composition on the rate of reaction. A 50/50 V/V isopropanol/water solvent mixture was prepared and 1cm3 of (CH3)3CCl was added. At specific instances, aliquots of the reaction mixture were withdrawn and quenched with acetone. In addition, phenolphthalein was added as an indicator. The
