Problem 72E
Reaction Mechanisms (Section)
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)→H20(I) + O2(g) + I - (ag) (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.

ANSWER:Step 1 of 4
a)
The equations for the decomposition reaction of hydrogen peroxide reaction catalysed by the iodide ion are shown below.
The catalysed reaction takes place in two steps here. They are, as follows;
