Vedclass · Answer

(B) The given reaction is $2SO_2 + O_2 	o 2SO_3$. The rate expression for this reaction is given by: $-\frac{1}{2} \frac{d[SO_2]}{dt} = -\frac{d[O_2]}{dt} = \frac{1}{2} \frac{d[SO_3]}{dt}$. We are given the rate of disappearance of $O_2$,which is $-\frac{d[O_2]}{dt} = 2.0 	imes 10^{-4} \ mol \ L^{-1}s^{-1}$. From the rate expression,we have: $-\frac{d[O_2]}{dt} = \frac{1}{2} \frac{d[SO_3]}{dt}$. Therefore,the rate of appearance of $SO_3$ is: $\frac{d[SO_3]}{dt} = 2 	imes (-\frac{d[O_2]}{dt}) = 2 	imes (2.0 	imes 10^{-4} \ mol \ L^{-1}s^{-1}) = 4.0 	imes 10^{-4} \ mol \ L^{-1}s^{-1}$.

For the reaction $2SO_2 + O_2 \to 2SO_3$,the rate of disappearance of $O_2$ is $2.0 \times 10^{-4} \ mol \ L^{-1}s^{-1}$. The rate of appearance of $SO_3$ is:
