Identify order of reaction if it's rate constant is $\mathrm{x} \mathrm{sec}^{-1}$.

Identify order of reaction if it's rate constant is $\mathrm{x} \mathrm{sec}^{-1}$.
  1. 3
  2. 2
  3. 0
  4. 1

Solution

Unit of Rate constant $(\mathrm{k})$ is $\mathrm{M}^{(1-\text { order })} \cdot \mathrm{sec}^{-1}$ $\mathrm{k}=\mathrm{x} \mathrm{sec}^{-1}$ (given) (By comparison) $1-$ order $=0$ Order $=1$
