Question

The chemical reaction 2O3 ------- 3O2 proceeds as follows:

O3 ------- O2 + O (fast)

O + O2 ------ 2O2 (slow)

The rate law expression should be

(a) r= k[O3]2 (b) r= [O3]2 [O2]-1 (c) r= k[O3] [O2] (d) unpredictable

Plz explain the answer.

Answer 1

the answer is not in the option. so the answer must be unpredictable.
