For a first order reaction, the concentration of reactant :

Assertion :For a first order reaction, the concentration of the reactant decreases exponentially with time. Reason: Rate of reaction at any time depends upon the concentration of the reactant at that time.

In a first order reaction, The concentration of reactant is reduced to 1/8th of the initial concentration in 75 minutea at 298 K. What is the half period of the reaction in minutes?
