The units of rate constant for first order reaction are
Options
- Amol L ⁻¹ ~s ⁻¹
- Bs ⁻¹
- CI mol ⁻¹ ~s ⁻¹
- DI ² mo ⁻² ~s ⁻¹
Correct answer
B. s ⁻¹
Step-by-step solution
For n th order reaction, the units of rate constant = ( mol L ⁻¹ )^ 1-n ~s ⁻¹ (where, n= order of reaction ) For Ist order reaction, the units of rate constant = ( mol L ⁻¹ )¹⁻¹ ~s ⁻¹= s ⁻¹
