Question

In the reaction, $A+2 B \longrightarrow 6 C+2 D$, if the initial rate $-\frac{d[A]}{d t}$ at $t=0$ is $2.6 	imes 10^{-2} \mathrm{M} \mathrm{sec}^{-1}$, what will be the value of $-\frac{d[B]}{d t}$ at $t=0$ ?

Professor PC Thomas Classes · Answer

$\begin{aligned} 	ext { Rate of reaction } & =\frac{	ext { Rate ofdisappearance/appearance }}{	ext { Stoichiometric coefficient }} \ & =-\frac{d[A]}{d t}=-\frac{1}{2} \frac{d[B]}{d t}=2.6 	imes 10^{-2} \ & =-\frac{1}{2} \frac{d[B]}{d t} \ 5.2 	imes 10^{-2} & =-\frac{d[B]}{d t}\end{aligned}$
