Question

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

Answer 1

Answer:

t1/2 will be double . t1/2= initial conc./2K

Answer 2

When initial concentration of a reactant is doubled the half life period of a zero order reaction is also doubled.

Explanation:

Zero order reaction : A reaction is said to be of zero order if the rate is independent of the concentration of the reactants, that means the rate is directly proportional to the zeroth power of the concentration of the reactants.

Half life period is the time taken to reduce the original reactants to half of its value.

$t_\frac{1}{2}=\frac{[a_0]}{2k}$

Thus half life for zero order is directly proportional to the initial concentration, as initial concentration of a reactant is doubled the half life period of a zero order reaction is also doubled.
