(D) For the reaction $2SO_2 + O_2 \to 2SO_3$,the rate expression is given by: $-\frac{1}{2} \frac{d[SO_2]}{dt} = \frac{1}{2} \frac{d[SO_3]}{dt}$. Since the stoichiometric coefficients of $SO_2$ and $SO_3$ are both $2$,the rate of disappearance of $SO_2$ is equal to the rate of appearance of $SO_3$. Therefore,the rate of appearance of $SO_3 = 1.28 \times 10^{-5} \ mol \ s^{-1}$.
