Solution

The correct option is D $k_{2} (\begin{matrix} \frac{k_{1}}{k_{- 1}} \end{matrix})$
$r = k_{2} [N_{2} O_{2}] [O_{2}]$ ....(i)
$\frac{k_{1}}{k_{- 1}} = \frac{[N_{2} O_{2}]}{{[N O]}^{2}} o r [N_{2} O_{2}] = \frac{k_{1}}{k_{- 1}} {[N O]}^{2} f r o m e q .$ (i)
$r = k_{2} \frac{k_{1}}{k_{- 1}} = {[N O]}^{2} [O_{2}]$
compair $r = k {[N O]}^{2} [O_{2}]$
$k = k_{2} \frac{k_{1}}{k_{- 1}}$
