For the first order reaction A B , The rate constant is 0 25 ~S ⁻¹ , if the concentration of A is reduced to half, the value of rate constant will be

Options

  1. A2 25 ~s ⁻¹
  2. B0.075 ~s ⁻¹
  3. C0 30 ~s ⁻¹
  4. D0 25 ~s ⁻¹

Correct answer

D. 0 25 ~s ⁻¹

Step-by-step solution

Rate constant for first order reaction is independent of initial concentration. Thus, k =0.25 ~s ⁻¹ .
