In a first order reaction, the concentration of the reactant, decreases from 0.8 M to 0.4 M in 15 minutes. The time taken for the concentration to change from 0.1 M to 0.025 M is
Text Solution
Verified by ExpertsThe correct answer is:
C
The concentration of the reactants decrease from 0.8 to 0.4 in 15 min i.e., 
min , concentration from 0.1 m to 0.025 will fall in 2 half lives so total time taken 
min .
