Vedclass · Answer

(A) For a general reaction $aA + bB \rightarrow cC + dD$,the rate of reaction is given by:Rate $= -\frac{1}{a} \frac{d[A]}{dt} = -\frac{1}{b} \frac{d[B]}{dt} = \frac{1}{c} \frac{d[C]}{dt} = \frac{1}{d} \frac{d[D]}{dt}$.For the given reaction $2A + B \rightarrow 3C + D$,the rate is:Rate $= -\frac{1}{2} \frac{d[A]}{dt} = -\frac{d[B]}{dt} = \frac{1}{3} \frac{d[C]}{dt} = \frac{d[D]}{dt}$.Comparing this with the options,option $A$ is $-\frac{1}{3} \frac{d[C]}{dt}$,which is incorrect because the rate should be $+\frac{1}{3} \frac{d[C]}{dt}$ for the product $C$.

For the reaction $2A + B \rightarrow 3C + D$,which of the following does not express the rate of reaction?
