For the first-order reaction `T_(av)` (average life), `T_(50)` (half-life) and `T_(75)` (time `75%` reaction) are in the ratio of

For the first-order reaction T_(av) (average life), T_(50) and T_(75) in the increasing order are :

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

The correct relation between t_(av) =average life and t_(1//2)= half life for a radioactive nuclei.

The correct relation between t_(av) =average life and t_(1//2)= half life for a radioactive nuclei.

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:

A first order of reaction is 75% complete in 18 minute. What is the half-life period for the reaction ?
