For reaction :
$2NO_2(g) + O_3(g) \to N_2O_5(g) + O_2(g)$
rate law is $R = K\, [NO_2]' [O_3]'$.
Which of these possible reaction mechanisms is consistent with the rate law?
Mechanism $I :$
$NO_2(g) + O_3(g) \to NO_3(g) + O_2(g)$ (slow)
$NO_3(g) + NO_2(g) \to N_2O_5(g)$ (fast)
Mechanism $II :$
$O_3(g) \rightleftharpoons O_2(g) + [O]$ (fast)
$NO_2(g) + [O] \to NO_3$ (slow)
$NO_3(g) + NO_2(g) \to N_2O_5$ (fast)
