Half-life period of a first order reaction is 1386 ~s . The specific rate constant of the reaction is
Options
- A5.0 10⁻³ ~s ⁻¹
- B0.5 10⁻² ~s ⁻¹
- C0.5 10⁻³ ~s ⁻¹
- D5.0 10⁻² ~s ⁻¹
Correct answer
C. 0.5 10⁻³ ~s ⁻¹
Step-by-step solution
Specific rate constant, k = 0.693 t _ 1 / 2 = 0.693 1386 =0.5 10⁻³ ~s ⁻¹
