Prove that in completing the first class reaction 3/4 Time taken, double the time taken to complete the semi-action

Mean time taken to complete the journey is

For a first order reaction, calculate the ratio between the time taken to complete three fourth of the reaction and the time taken to complete half of the reaction.

For a first order reaction, calculate the ratio between the time taken to complete three-fourth of the reaction and the time taken to complete half of the reaction.

For a first order reaction, calculate the ratio between the time taken to complete three-fourth of the reaction and the time taken to complete half of the reaction.

The half life period of a first order reaction is 3 minutes. Calculate the time taken to complete 75% of the initial concentration.

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.

The time for half life of a first order reaction is 1 hr. what is the time taken for 87.5% completion of the reaction?

The time for half life of a first order reaction is 1 hr. what is the time taken for 87.5% completion of the reaction?
