If the half life of a first order reaction in A is 2 min, how long will it take A to reach a) 25 percent of its initial concentration b) 10 percent of its initial concentration?

If half life period for a first order reaction in A is 2 minutes, how long will it take [A] to reach (i) 25% of its initial concentration ii) 10% of its initial concentration?

If the half-life period of a first order reaction in A is 2 minutes, how long will it take [A] to reach 25% of its initial concentration ?

If the half-life period of a first order reaction in A is 2 minutes, how long will it take [A] to reach 25% of its initial concentration ?

The half life period of 1st order reaction of A is 2 minutes. How long will it take to reach at 25% of its initial concentration.

If the half life period for a reaction in A is 100 min . How long will it take [A] to reach 25 % of its initial concentration ?

For a first order reactions, the half -life is 10 mins. How much time in minutes will it take to reduce the concentration of reactant to 25% of its original concentration ?

For a first order reactions, the half -life is 10 mins. How much time in minutes will it take to reduce the concentration of reactant to 25% of its original concentration ?

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.
