A complex reaction takes place in following steps.

$$ \begin{aligned} & \mathrm{NO}_2 \mathrm{Cl}_{(\mathrm{g})} \longrightarrow \mathrm{NO}_{2(\mathrm{~g})}+\mathrm{Cl}_{(\mathrm{g})} \text { (slow) } \\ & \mathrm{NO}_2 \mathrm{Cl}_{(\mathrm{g})}+\mathrm{Cl}_{(\mathrm{g})} \longrightarrow \mathrm{NO}_{2(\mathrm{~g})}+\mathrm{Cl}_{2(\mathrm{~g})} \text { (fast) } \end{aligned} $$

Identify rate law equation for this reaction.

$\mathrm{r}=\mathrm{k}\left[\mathrm{NO}_2 \mathrm{Cl}\right]$

$\mathrm{r}=\mathrm{k}\left[\mathrm{NO}_2\right][\mathrm{Cl}]$

$\mathrm{r}=\mathrm{k}\left[\mathrm{NO}_2\right]^2$

$\mathrm{r}=\mathrm{k}\left[\mathrm{NO}_2 \mathrm{Cl}\right]^2$
