Vedclass · Answer

(B) For the reaction $2 A + 3 B ightarrow 4 C + D$,the rate expression is given by: $-\frac{1}{3} \frac{d[B]}{dt} = +\frac{1}{4} \frac{d[C]}{dt}$ Given that the rate of appearance of $C$ is $\frac{d[C]}{dt} = 2.8 	imes 10^{-3} \ mol \ L^{-1} \ s^{-1}$. The rate of disappearance of $B$ is $-\frac{d[B]}{dt}$. From the rate expression: $-\frac{d[B]}{dt} = \frac{3}{4} \frac{d[C]}{dt}$ Substituting the given value: $-\frac{d[B]}{dt} = \frac{3}{4} 	imes (2.8 	imes 10^{-3}) \ mol \ L^{-1} \ s^{-1}$.

For an elementary reaction $2 A + 3 B \rightarrow 4 C + D$,the rate of appearance of $C$ at time $t$ is $2.8 \times 10^{-3} \ mol \ L^{-1} \ s^{-1}$. The rate of disappearance of $B$ at time $t$ will be:
