A) Rate of disappearance of A = Rate of formation of D
B) Rate of formation of \[C=\frac{2}{3}\times \]Rate of disappearance of B
C) Rate of formation of \[D=\frac{1}{3}\times \]Rate of disappearance of B
D) Rate of disappearance of \[A=2\times \]Rate of formation of C
Correct Answer: D
Solution :
For the reaction, \[A+3B\xrightarrow{{}}2C+D\] \[\therefore \] \[-\frac{d[A]}{dt}=-\frac{d[B]}{3\,dt}=+\frac{d[C]}{2dt}=+\frac{d[D]}{dt}\] \[\therefore \] \[-\frac{d[A]}{dt}=+\frac{d[C]}{2dt}\] Rate of disappearance of \[A=\frac{1}{2}\times \]rate of formation of C. All other relations are correct.
