(B) The rate of reaction is given by the expression: $-\frac{1}{3} \frac{d[X]}{dt} = \frac{1}{2} \frac{d[Y]}{dt} = \frac{d[Z]}{dt}$ Given that the rate of disappearance of $X$ is $-\frac{d[X]}{dt} = 7.2 \times 10^{-3} \ mol \ L^{-1} \ s^{-1}$. From the rate expression,we have: $\frac{1}{2} \frac{d[Y]}{dt} = -\frac{1}{3} \frac{d[X]}{dt}$ Therefore,the rate of formation of $Y$ is: $\frac{d[Y]}{dt} = \frac{2}{3} \times (-\frac{d[X]}{dt}) = \frac{2}{3} \times 7.2 \times 10^{-3} = 4.8 \times 10^{-3} \ mol \ L^{-1} \ s^{-1}$.
