(A) For the reaction $2SO_{2(g)} + O_{2(g)} \rightarrow 2SO_{3(g)}$,the rate of reaction is expressed as:$Rate = -\frac{1}{2} \frac{d[SO_2]}{dt} = -\frac{d[O_2]}{dt} = \frac{1}{2} \frac{d[SO_3]}{dt}$Given that $-\frac{d[O_2]}{dt} = 2.5 \times 10^{-4} \, mol \, L^{-1} \, s^{-1}$.Equating the terms for $SO_2$ and $O_2$:$-\frac{1}{2} \frac{d[SO_2]}{dt} = -\frac{d[O_2]}{dt}$$-\frac{d[SO_2]}{dt} = 2 \times (-\frac{d[O_2]}{dt})$$-\frac{d[SO_2]}{dt} = 2 \times (2.5 \times 10^{-4} \, mol \, L^{-1} \, s^{-1}) = 5 \times 10^{-4} \, mol \, L^{-1} \, s^{-1}$.
