Problem

A proposed mechanism for the decomposition of ozone is shown. Step 1 NO(g) + O3(g) → NO2(g) + O2(g) (slow) Step 2 NO2(g) + O(g) → NO(g) + O2(g) (fast) Which of the following is the rate law that is consistent with this mechanism? (a) k[NO]2[O3]k[\text{NO}]^{2}[\text{O}_3] (b) k[O3]2k[\text{O}_3]^{2} (c) k[NO][O3]k[\text{NO}][\text{O}_3] (d) k[NO2][O3]k[\text{NO}_2][\text{O}_3]
