Q. The rate of a reaction is expressed in different ways as follows $+ \frac{1}{2}\frac{d\lbrack C\rbrack}{dt} = - \frac{1}{5}\frac{d\lbrack D\rbrack}{dt} = + \frac{1}{3}\frac{d\lbrack A\rbrack}{dt} = - \frac{d\lbrack B\rbrack}{dt}$ The reaction is
A) $4A + B \rightarrow 2C + 3D$
B) $B + 5D \rightarrow 3A + 2C$
C) $4A + 2B \rightarrow 2C + 3D$
D) $B + \frac{1}{2}D \rightarrow 4A + 2C$
Explanation
(b)
$B + 5D \rightarrow 3A + 2C$
$- \frac{d\lbrack B\rbrack}{dt} = - \frac{1}{5}\frac{d\lbrack D\rbrack}{dt} = + \frac{1}{3}\frac{d\lbrack A\rbrack}{dt} = + \frac{1}{2}\frac{d\lbrack C\rbrack}{dt}$
