Iodide is oxidized by hydrogen peroxide according to the following mechanism:

Iodide is oxidized by hydrogen peroxide according to the following mechanism:

H 2 O 2 + I^ – → H 2 O + OI^ – (slow)

H^+ + OI^ – → HOI (fast)

HOI + H^+ + I^ – → I 2 + H 2 O (fast)

(b) What is the molecularity of each step?

(c) Write the rate equation for the rate-determining step.

(d) What are the intermediates in this reaction? (If none, write “none.”)
