    If \[3A\to 2B,\] then the rate of reaction of \[+\frac{d(B)}{dt}\]is equal to [CBSE PMT 2002]

    A)                 \[+2\frac{d(A)}{dt}\]     

    B)                 \[-\frac{1}{3}\frac{d(A)}{dt}\]

    C)                 \[-\frac{2}{3}\frac{d(A)}{dt}\]   

    D)                 \[-\frac{3}{2}\frac{d(A)}{dt}\]

    Correct Answer: C

    Solution :

                    \[-\frac{1}{3}\frac{d[A]}{dt}=\frac{1}{2}\frac{d[B]}{dt}\]  \[\therefore \frac{d[B]}{dt}=-\frac{2}{3}\frac{d[A]}{dt}\]
