I have a reaction that has three elementary steps: 3I- +S2O82- ---> I3- + 2 SO42- (this is the RLS) I3 + 2 S2O32- ---> 3 I- + S4O62- starch + I3- ---> starch - I3- complex. (color change to indicate rxn is over) In multiple trials I change the concentrations to see its effect on the rate of the rxn. But the reagents I'm using in this rxn are: (1) starch, Na2S2O3 , KI, KNO3 , and (2) (NH4)2S2O8...
