NEETChemistryChemical KineticsMCQ+4 / −1
When initial concentration of the reactant is doubled, the half-life period of a zero order reaction
  1. A
    is halved
  2. B
    is doubled
  3. C
    is tripled
  4. D
    remains unchanged.

Correct answer: B

Half life of zero order
t1/2 = [A]02k{{{{{\left[ A \right]}_0}} \over {2k}}}2k[A]0​​

∴\therefore∴ t1/2 ∞\infty ∞ [A]0

∴\therefore∴ If [A]0 = doubled then, t1/2 = doubled.
