Question

The rate constant of a reaction is $2.3\times 10^{-2}mo{l}^{-2}{L}^{2}mi{n}^{-1}$. The order of reaction is

• A. zero
• B. 1
• C. 2
• D. 3

Answer 1

Answer: (D)

Unit of rate constant $={\left(\frac{litre}{mol}\right)}^{n-1}{s}^{-1}$

If $n=3$, then the unit of rate constant is $mo{l}^{-2}{L}^2{s}^{-1}$.

Therefore, the order of reaction is three
