Which of the following statements is false

A

a fast reaction has a large rate constant and short half-life

B

Half life depends on concentration of reactants for first order reaction.

C

For a first order reaction,the half-life is independent of concentration

D

The half-life of a reaction is, the time required for the reaction to go to half of the intial concentration of reactants

Text Solution

Verified by Experts

The correct Answer is:
