The reaction, $\mathrm{2NO(g) + O_2(g) \rightarrow 2NO_2(g)}$ proceeds via the following steps
$\mathrm{NO + NO \xrightarrow{k_a} N_2O_2}$; $\mathrm{N_2O_2 \xrightarrow{k_{a^\prime}} NO + NO}$; $\mathrm{N_2O_2 + O_2 \xrightarrow{k_b} NO_2 + NO_2}$
The rate of this reaction is equal to
(a)$2k_b[\mathrm{NO}][\mathrm{O_2}]$
(b)$(2k_ak_b[\mathrm{NO}]^2[\mathrm{O_2}])/(k_a + k_b[\mathrm{O_2}])$
(c)$2k_b[\mathrm{NO}]^2[\mathrm{O_2}]$
(d)$k_a[\mathrm{NO}]^2[\mathrm{O_2}]$
