When initial concentration of the reactant is doubled, what happens to the half-life period of a zero order reaction?
  1. It is tripled.
  2. It is doubled.
  3. It is halved.
  4. It remains unchanged.

Solution

Order of reaction =0

Half life 
t12 = A02Kt12∝A0
∴ Initial concentration doubled then half-life i.e   t 1 2  becomes double
