Chapter 13.8, Problem 13.11E

The iodide-ion-catalyzed decomposition of hydrogen peroxide, H₂O₂, is believed to follow the mechanism

$\begin{array}{llll}{\text{H}}_2{\text{O}}_2+{\text{I}}^{-}\hfill & \stackrel{k_1}{\to }\hfill & {\text{H}}_2\text{O}+{\text{IO}}^{-}\hfill & (\text{slow})\hfill \\ {\text{H}}_2{\text{O}}_2+{\text{IO}}^{-}\hfill & \stackrel{k_2}{\to }\hfill & {\text{H}}_2\text{O}+{\text{O}}_{\text{2}}+{\text{I}}^{-}\hfill & (\text{fast})\hfill \end{array}$

What rate law is predicted by this mechanism? Explain.
