The half-life of a reaction (t 1/2) is the time required for one-half of a given amount of reactant to be consumed. In each succeeding half-life, half of the remaining concentration of the reactant is consumed.

WebThe half-life of a reaction is the time required for a reactant to reach one-half its initial concentration or pressure. For a first-order reaction, the half-life is independent of concentration and constant over time. Created by Jay. WebIn a first order reaction, the half-life is always constant throughout a reaction. For a second-order reaction, the half-life doubles as the concentration halves. And for a zero-order reaction, the half-life halves as the concentration halves.

WebSep 2, 2015 · Zero order reaction has half life directly proportional to its initial concentration. If [A]° (initial concentration) , K (rate constant) Then. T (1/2)= [A]° / 2K . But . For first order reaction, T (1/2)= 0.693 / K. And you can get now that in first order reaction the half life is totally independent of the initial concentration. WebThe half-life depends on the order of the reaction, and it is obtained from the corresponding integrated rate law.
