Question

The decomposition of hydrogen peroxide is catalyzed by
iodide ion. The catalyzed reaction is thought to proceed
by a two-step mechanism:
H₂O₂₍aq) + I ^- (aq)---->H₂O(l) + IO^- (aq) (slow)
IO^- (aq) + H₂O₂(aq)--->H₂O(l) + O₂(g) + I ^- (aq) (fast)
(a) Write the chemical equation for the overall process.
(b) Identify the intermediate, if any, in the mechanism.
(c) Assuming that the first step of the mechanism is rate
determining, predict the rate law for the overall process.
