This is called the rate constant and its value changes with temperature. Using results of certain temperature I should be able to calculate a value for 'k'. Using the following values: [Br03] = 0.008 [Br -] = 0.01 [H+]2 = (0.1)2 = 0.01 At room temperature, calculated reaction rate for the values are to be 0.0221 seconds-1. Substituting the above values into the rate equation in order to calculate the constant 'k', Firstly we need to rearrange the equation to make 'k' the subject: Reaction Rate = k[Br03] [Br-] [H+]2 k = k = k = !"#$%&'( !"#$ [!"!"] [!"!][!!]! !.!""# (!.!!") (!.!") (!.!") !.!""# (! ! !"!!) k = 27625 The units for 'k' vary depending on the reaction investigated. In this case they are worked out as
