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 $\mathrm{Cl}_2$.

Correct answer
A
Rate $=\mathrm{k}\left[\mathrm{NO}^2\left[\mathrm{Cl}_2\right]\right.$
B
Rate $=\mathrm{k}[\mathrm{NO}]\left[\mathrm{Cl}_2\right]$
C
Rate $=\mathrm{k}[\mathrm{NO}]^2$
D
Rate $=\mathrm{k}\left[\mathrm{Cl}_2\right]$

Solution

\begin{array}{|l|l|l|} \hline Std.12 & Ch-6 & Subtopic-6.3 \\ \hline \end{array}

Hence, the correct answer is option: 'A'.
