Abstract: To determine the rate law in each reaction and find the reaction rate, an experiment was conducted with acetone, acid, iodine, and water. By using different concentrations of each substance, a number of 4 times, the rate was giving of each reaction and recorded the times it took to react. Based off the results from the first four reactions, further data was collect with a fifth reaction. Using 15mL of acetone, 10mL of hydrochloric acid, 5mL of iodine, and 20mL of water, we got a rate of 8.77× 10-7. The reaction rate was much higher than the rates of the previous reactions. So essentially the amount of water determines the rate, and the amount of acetone determines how long it takes the solution to react and become completely clear. …show more content…

Then the time of each reaction was recorded when the solution was completed and turned clear. Reaction rate was then calculated using the initial concentration of I2 and time recorded. If reaction rate increases, the reaction is done faster and the reaction time decreases. The first order reaction is a reaction depending only on the concentration of two reactants. Determination of the rate law and activation energy of a chemical reaction requires a number of steps. By varying the concentrations of reactants in the iodination of acetone it was determined that the reaction is first order with respect to both acetone and hydrochloric acid concentration and zero order with respect to iodine concentration. The error in all parts of this experiment is relatively small. This reaction is fast enough to be performed in a reasonable amount of time, but not so fast that it is difficult to duplicate this

The reaction was repeated 3 times and average rate noted. From these rates a graph was plotted which describes the relationship of the pressure produced and number of drops added. The reaction rates were measured by Kpa/min and were written to 4 figures for precise results. Time was measured by stop watch. Table 4 shows a summary of all the groups which participated in the lab session.

The topic the scientists will be conducting is called Alka-Seltzer Tablets, Rate of Reaction. Here the scientists will be testing the reaction time of Alka-Seltzer tablets. The scientists will be testing that by taking various substances and dropping in one Alka-Seltzer tablet per each cup of liquid. The scientists will be testing the variables include the temperature such as cold water, salt water at room temperature, room temperature water, vinegar water at room temperature that’s the independent variables. The dependent variable is the rate of dissolving in seconds.

They tested how the temperature would affect the rate of reaction. This was observed by the amount of time it took for the solution to change colors. For many chemical reactions there is an optimum temperature at which the chemicals will react with each other. As was found in their experiment, the temperature affected the rate of reaction. (Deoudes, 2010).

ABSTRACT To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. In this experiment we examined how increasing the volume of the extract added to the reaction would affect the rate of the reaction. The enzyme used was horseradish peroxidase which helps catalyze hydrogen peroxide. Using different pH levels, the absorbance rate of the reaction was measured to see at which condition the enzyme worked best. The rates of absorption were calculated using a spectrophotometer in 20 second intervals up to 120 seconds.

The average reaction time for Run 2 without catalysis was 73.68s and with catalyst was 12.13s, which have a big difference, the average reaction time for Run 2 with he catalyst was much faster than the one without the catalyst. Based on the result of average reaction time, the catalyst helps reaction to increase the rate of the reaction. Collision theory states that the particles in the reaction should collide with a certain minimum energy, which is called the activation energy. If

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.

Use these results to determine the product concentration, using Beer-Lambert’s Law: A= ɛCl (where A is the absorbance, ɛ is the molar absorptivity, C is the product concentration and l is the length of solution that the light passes through). Calculate the product concentrations at every minute for 10 minutes for all 7 of the test tubes using Beer-Lambert’s Law. Plot a graph of product concentration vs. time and then use the gradients of the 7 test tubes to determine the velocities of the reaction. After calculating the velocities, plot a Michaelis-Menten graph of velocity vs. substrate concentration.

AIM To design an investigation to study the kinetics of a reaction of your choice RESEARCH QUESTION With respect to hydrochloric acid (HCl), what is the order of reaction in the reaction between HCl and calcium carbonate (CaCO3) determined by changing the concentration of HCl and measuring the volume of carbon dioxide gas (CO2) collected in 30 seconds whilst keeping the mass of the powdered CaCO3 constant and the temperature of the reaction system at 25oC? BACKGROUND INFORMATION Calcium carbonate (CaCO3) is a chemical compound that is commonly found in rocks such as chalk, limestone, marble and travertine in all parts of the world. It also used as a form of medicine as a dietary supplement for a person with insufficient calcium intake because calcium is needed by the body for healthy bones, muscles, nervous system, and heart. CaCO3 is also used as an antacid to relieve

In this experiment rate of reaction with different reactants concentration: KI (0.010 M), KBrO3 (0.040 M), and HCl (0.10 M) will be observed. So, this is reaction between iodide and bromate ion under acidic conditions: 6 I- (aq) +BrO3-(aq)+ H+(aq)→ 3I2(aq) + Br-(aq)+ 3H2O The end of the reaction, will be determined by observing color change of solution. Thus, solution should shange color to blue.
