The correct difference between first and second order reactions is that

Options

A. A first order reaction can catalyzed, a second-order reaction cannot be catalyzed
B. The half -life of a first-order reaction does not depend on `[A]_(0)`, the half-life of a second-order reaction does depend on `[A]_(0)`
C. The rate of first-order reaction does not depend on reactant concentrations, the rate of a second-order reaction does depend on reactant concentrations.
D. The rate of frist-order reaction does not depend on reactant concentrations, the rate of a second-order reaction does not depend on reactant concentrations

Answer

B

Explanation

For first order reaction `t_(1//2)=(0.693)/(K),` which is independent of initial concentration of reactant.
For second order reaction , `t_(1//2)=(1)/(k[A_(0)])`, which depend pm initial concentration of reactant.
