The mechanism for the reaction 2 H2O2(aq) à 2 H2O(l) + O2(g) in the presence of I–(aq) is proposed to be:

Step 1: H2O2(aq) + I–(aq) à H2O(l) + OI–(aq)                                   (slow)

Step 2: H2O2(aq) + OI–(aq) à H2O(l) + O2(g) + I–(aq)                       (fast)

What is the rate law for the overall reaction?

            a. Rate = k[H2O2]2

            b. Rate = k[H2O2][I–]

            c. Rate = k[H2O2]2[I–]/[H2O]

            d. Rate = k[H2O2][OI–]

            e. Rate = k[H2O2]
