Chemistry - Chemical Kinetics Question with Solution | TestHub

Given that the rate of reaction is proportional to the square of $[{\mathrm{NO}}_2]$, the order of the reaction with respect to ${\mathrm{NO}}_2$ is $2$.

Given that the rate of reaction is independent of $[\mathrm{CO}]$, the order of the reaction with respect to $\mathrm{CO}$ is $0$.

The rate law equation can be written as $r=k[{\mathrm{NO}}_2{]}^2[\mathrm{CO}{]}^0$.

Answer: $\mathrm{r}=\mathrm{k}{\left[{\mathrm{NO}}_2\right]}^2[\mathrm{CO}{]}^0$
