S2O82-(aq) + 2I-(aq) ----------> 2SO42-(aq) + I2(aq) (I)

Rate = k [S2O82-]x [I-]y

Rate1 = k [S2O82-]x [I-]y

Experiment data
Experiment: 0.20M NaI,0.20M NaCl, 0.010M Na2S2O3,2% Starch,0.20M K2SO4, 0.20 M K2S2O8
Used 2ml = 20 drops of each solution for the experiment 1.
Time for Exp 2 and 3 are 101 sec and 96 seconds
Experiment2 20 drops 20 drops 20 drops 20 drops 0 drops 40 drops

Experiment3 40 drops 0 drops 20 drops 20 drops 20 drops 20 drops
