How much time in minutes passes between 99% to 99.9% completion of a f – InterviewSolution

1.	How much time in minutes passes between 99% to 99.9% completion of a first order reaction with half life 0.3010"min"^(-1)?
Answer» SOLUTION :`(0.693/0.3010)xxt_(1)=2.303xxlog(100/1)t_(1)=2,0.693/0.310xxt_(2)=2.303xxlog(100/0.1)t_(2)=3` `DELTA=(t_(2)-t_(1))=(3-2)=1,Deltat=1`
