The decomposition of hydrogen 2 peroxide is catalyzed by iodide ion. The reaction mechanism is thought to be H,O2(aq) + l(aq) → H,0(I) + 10 (aq) 10(aq) + H,O2(aq) → H,0(I) + O2(g) + I'(aq) At 25°C, the first step is slow relative to the second step. What is the rate law predicted by the reaction mechanism? Is there a reaction intermediate?

Question
The decomposition of hydrogen
2 peroxide is catalyzed by iodide ion. The
reaction mechanism is thought to be
H,O2(aq) + I(aq) → H,0(I) + 10(aq)
10(aq) + H,O2(aq) → H,O(I) + O2(g) + I(aq)
At 25°C, the first step is slow relative to the
second step. What is the rate law predicted
by the reaction mechanism? Is there a
reaction intermediate?
