The reaction $\displaystyle 2 \mathrm{NO}+\mathrm{Br}_2 \rightarrow 2 \mathrm{NOBr}$
takes places through the mechanism given below:
$$\begin{aligned}
& \mathrm{NO}+\mathrm{Br}_2 \Leftrightarrow \mathrm{NOBr}_2 \text { (fast) } \\
& \mathrm{NOBr}{ }_2+\mathrm{NO} \rightarrow 2 \mathrm{NOBr} \text { (slow) }
\end{aligned}
$$
The overall order of the reaction is $\displaystyle \_\_\_\_$.
