Show that the following two-step mechanism is consistent with the experimentally determined rate law of rate $=k{\left[\text{NO}\right]}^2\left[{\text{Br}}_{\text{2}}\right]$ for the reaction of nitric oxide and bromine: $2\text{NO}\left(g\right)+{\text{Br}}_{\text{2}}\left(g\right)\to 2\text{NOBr}\left(g\right):$

$Step1:\text{ NO}\left(g\right)+{\text{Br}}_{\text{2}}\left(g\right)\underset{k_{-1}}{\overset{k_1}{\rightleftarrows }}{\text{NOBr}}_{\text{2}}\left(g\right)\left(\text{fast}\right)$

$Step\text{ 2}:{\text{ NOBr}}_{\text{2}}\left(g\right)+\text{NO}\left(g\right)\underset{}{\overset{k_2}{\rightleftarrows }}{\text{2NOBr}}_{}\left(g\right)\left(\text{slow}\right)$
