Half-life `(t_(1))` of the first order reaction and half-life `(t_(2))` of the second order reaction are equal. Hence ratio of the rate at the start of the start of the reaction:

Half-life t_(1//2) of first order reaction is______

Half life ( t_1 ) of the first order reaction and half life ( t_2 ) of the 2 ""^(nd) order reaction are equal. If initial concentration of reactants in both reaction are same then ratio of the initial rate of the reaction

Half life ( t_1 ) of the first order reaction and half life ( t_2 ) of the 2 ""^(nd) order reaction are equal. If initial concentration of reactants in both reaction are same then ratio of the initial rate of the reaction

Half-life period of any first order reaction is

For a first order reaction, the half-life period is
