For a first order reaction, 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?

Answer:

20.00

Solution:

It takes two half-lives to reduce the concentration of reactant to $25 %$ of its original concentration.
Hence, total time taken $= 10 + 10$
$= 20$ minutes.
