Rate of first order reaction A product is 0.01 ~mol dm ⁻³ ~s ⁻¹ , calculate rate constant if concentration of reactant is 0.2 M ?

Options

  1. A0.05 sec ⁻¹
  2. B0.1 sec ⁻¹
  3. C0.5 sec ⁻¹
  4. D0.01 sec ⁻¹

Correct answer

A. 0.05 sec ⁻¹

Step-by-step solution

r = K ( A )0.01=K(0.2) K = 0.01 0.20 =0.05 sec ⁻¹
