Rate of disappearance of $B = 2 	imes$ Rate of appearance of $C$

Vedclass · Answer

(C) For the reaction $A + B 	o 2C + D$,the rate of reaction is given by:$Rate = -\frac{d[A]}{dt} = -\frac{d[B]}{dt} = \frac{1}{2} \frac{d[C]}{dt} = \frac{d[D]}{dt}$From this expression:$1$. Rate of disappearance of $A = -\frac{d[A]}{dt}$$2$. Rate of disappearance of $B = -\frac{d[B]}{dt}$$3$. Rate of appearance of $C = \frac{d[C]}{dt}$$4$. Rate of appearance of $D = \frac{d[D]}{dt}$Comparing these:- Rate of disappearance of $A = 	ext{Rate of disappearance of } B$ (Correct)- Rate of disappearance of $A = 	ext{Rate of appearance of } D$ (Correct)- Since $-\frac{d[B]}{dt} = \frac{1}{2} \frac{d[C]}{dt}$,it implies $	ext{Rate of disappearance of } B = \frac{1}{2} 	imes 	ext{Rate of appearance of } C$ (Correct)- Therefore,the statement $	ext{Rate of disappearance of } B = 2 	imes 	ext{Rate of appearance of } C$ is incorrect.
