Identify rate law expression for $$2 \mathrm{NO}_{(\mathrm{g})}+\mathrm{Cl}_{2(\mathrm{~g})} \rightarrow 2 \mathrm{NOCl}_{(\mathrm{g})}$$ if the reaction is second order in $$\mathrm{NO}$$ and first order in $$\mathrm{Cl}_2$$.

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

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

$$\mathrm{Rate}=\mathrm{k}[\mathrm{NO}]^2$$

Rate $$=\mathrm{k}\left[\mathrm{Cl}_2\right]$$
