Question

A mechanism for a naturally occurring reaction that destroys ozone is:
Step 1: O3(g) + HO(g) HO2(g) + O2(g)
Step 2: HO2(g) + O(g) HO(g) + O2(g)
What is the molecularity of the overall reaction?

Select one:

A. bimolecular

B. unimolecular

C. none of these because molecularity is the difference of the exponents in the rate law

D. none of these because molecularity only refers to elementary steps
