For a first order reaction, it takes 16 min to complete 50% reaction. – InterviewSolution

1.	For a first order reaction, it takes 16 min to complete 50% reaction. How much time does it take to complete 75% reaction?
Answer» Solution :`K=0.693/t_(0.5)=0.693/16=0.0433min^-1` Time required to COMPLETE` 75%`REACTION, `t_(0.75)=2.303/K"log"100/(100-75)=2.303/0.0433"log"100/25=53.187xx0.06021=32`MINUTES.
