(D) The rate expression for the given reaction $2 \ NO_{(g)} + O_{2_{(g)}} \rightarrow 2 \ NO_{2_{(g)}}$ is given by: $-\frac{1}{2} \frac{d[NO]}{dt} = \frac{1}{2} \frac{d[NO_2]}{dt}$. The rate of consumption of $NO_{(g)}$ is defined as $-\frac{d[NO]}{dt}$. From the expression,$-\frac{d[NO]}{dt} = \frac{d[NO_2]}{dt}$. Given that $\frac{d[NO_2]}{dt} = 0.052 \ mol \ dm^{-3} \ s^{-1}$,Therefore,$-\frac{d[NO]}{dt} = 0.052 \ mol \ dm^{-3} \ s^{-1}$.
