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

Solution

Rate law for the reaction, \(2 \mathrm{NO}+\mathrm{Cl}_2 \longrightarrow 2 \mathrm{NOCl}\) is rate \(=\mathrm{k}\left[\mathrm{NO}\right]^2\left[\mathrm{Cl}_2\right]\).
