For the reaction, $\mathrm{NO}_{2(\mathrm{~g})}+\mathrm{CO}_{(\mathrm{g})} \longrightarrow \mathrm{NO}_{(\mathrm{g})}+\mathrm{CO}_{2(\mathrm{~g})}$ rate of reaction is proportional to square of $\left[\mathrm{NO}_2\right]$ and independent of [CO]. What is the rate law equation?

A
$\mathrm{r}=\mathrm{k} \frac{\left[\mathrm{NO}_2\right]^{\frac{1}{2}}}{[\mathrm{CO}]}$
B
$\mathrm{r}=\mathrm{k}\left[\mathrm{NO}_2\right]^2[\mathrm{CO}]^0$
C
$\mathrm{r}=\frac{1}{2} \mathrm{k}\left[\mathrm{NO}_2\right][\mathrm{CO}]$
D
$\mathrm{r}=\mathrm{k}\left[\mathrm{NO}_2\right]^2[\mathrm{CO}]$
