Chemistry - Chemical Kinetics Question with Solution | TestHub

For the given chemical equation, we have

$-\frac{1}{{\text{V}}_{\text{A}}}\frac{\text{d}\left[\text{A}\right]}{\text{d}\text{t}}=\frac{1}{{\text{V}}_{\text{B}}}\frac{\text{d}\left[\text{B}\right]}{\text{d}\text{t}}$

i.e.$-\frac{1}{\left(1∕2\right)}\frac{\text{d}\left[\text{A}\right]}{\text{d}\text{t}}=\frac{1}{2}\frac{\text{d}\left[\text{B}\right]}{\text{d}\text{t}}$

Hence,$-\frac{\text{d}\left[\text{A}\right]}{\text{d}\text{t}}=\frac{1}{4}\frac{\text{d}\left[\text{B}\right]}{\text{d}\text{t}}$
