Question

Consider this reaction.
2NO2(g) + O3(g) → N2O5(g) + O2(g)
The reaction of nitrogen dioxide and ozone represented is first order in NO2(g) and in O3(g). Which of these possible reaction mechanisms is consistent with the rate law?
Mechanism I. NO2 + O3 → NO3 + O2 slow
NO3 + NO2 → N2O5 fast
Mechanism II. O3 ⇌ O2 + O fast
NO2 + O → NO3 slow
NO3 + NO2 → N2O5 fast

A.

I only

B.

II only

C.

both I and II

✓ Correct
D.

neither I nor II
