The half -life of a first order reaction is 40min . Calculate the time taken by the reaction to reach 78% of completion . If the initial concentration of the reactant is doubled , how long will it take to reach 50% completion . Justify your answer.

Half - life of a first order reaction is 15 min . Calculate rate constant of the reaction and the time required to complete 80% of the reaction. If the initial concentration of the reactant is doubled , how long will it take to reach 50% completion ? Give reason.

t_(1//2) of a first order reaction is 15 min . Calculate the time for 80% completion of the reaction . If the initial concentration of the reactant is doubled , calculate the time taken for 80% completion of the reaction Give reasons.

When initial concentration of the reactant is doubled, the half-life period of a zero order reaction -

When initial concentration of the reactant is doubled, the half-life period of a zero order reaction-
