The half-life for a zero order reaction having 0 . 02   M initial concentration of reactant is 100   s . The rate constant (in mol   L - 1 s - 1 ) for the reaction is

Options

  1. A1 . 0 × 10 - 4
  2. B2 . 0 × 10 - 4
  3. C2 . 0 × 10 - 3
  4. D1 . 0 × 10 - 2

Correct answer

A. 1 . 0 × 10 - 4

Step-by-step solution

t 1 / 2 zero  = [ A ] 0 2 K 100 s = 0 . 02 M 2 K K = 0 . 02 M 2 × 100 = 1 × 10 - 4   mol   L - 1 s - 1
