When initial concentration of the reactant is doubled, the half-life period of a zero-order reaction

Options

  1. AIs tripled
  2. BIs doubled
  3. CIs halved
  4. DRemains unchanged

Correct answer

B. Is doubled

Step-by-step solution

Half-life of zero order t 1 / 2 = [ A 0 ] 2 k i.e., t 1 / 2 ∝ a or ( A 0 ) t 1 / 2 will be doubled on doubling the initial concentration.
