Question

The following mechanism has been proposed for the reaction of $N O$ with $B r_{2}$ to from $N O B r$
${N O}_{(g)} + {B r}_{2} (g) f a s t ⇌ {N O B r}_{2 (g)}$
$N O {B r}_{2 (g)} + {N O}_{(g)} s l o w ⇌ {2 N O B r}_{(g)}$
If the seconds step is the rate determining step,the order of the reaction is:
