Determine the oder of the reaction in H2O2 and KI. Explain how you arrived at your answer. Calculate the rate constant, k, and write the rate law expression for the catalyzed decomposition of hydrogen peroxide.

The four initial rates I have from H2O2 and KI are:
1) 1.15 X 10^-5
2) 2.66 X 10^-6
3) 2.11 X 10^-6
4) 1.06 X 10^-5

Mixture:
1) .704 mol/L H2O2 and .1 mol/L KI
2) .704 and .05
3) .352 and .1
4) .704 and .1
