Question

A possible mechanism for the conversion of ozone to oxygen in the upper atmosphere is
O3(g) ⇌ O2(g) + O(g) (fast equilibrium)
O(g) + O3(g) ⇌ 2O2(g) (slow)
Which rate law is consistent with this mechanism?

A.

Rate = k[O3]

B.

Rate = k[O3]^2

C.

Rate = k[O3][O]

D.

Rate = k[O3]^2[O2]–1
