For a reaction, \mathrm{ a A+b B \rightarrow c C}


We know, rate of reaction at any given time

\mathrm{ =-\frac{1}{a} x \frac{d[A]}{d t}=-\frac{1}{b} x \frac{d[B]}{d t}=\frac{1}{c} x \frac{d[C]}{d t}}


Hence, \mathrm{-\frac{d[A]}{d t}=-\frac{1}{2} x \frac{d[B]}{d t}=\frac{1}{2} x \frac{d[C]}{d t}}


\mathrm{\Rightarrow-2 x \frac{d[A]}{d t}=\frac{d[C]}{d t} }.
