Half life period of a first order reaction is 100 min. After 144.3 min

1.	Half life period of a first order reaction is 100 min. After 144.3 min concentration of the reactant is reduced to of the original concentration
Answer» `1//e` `1//e^(2)` `10%` `20%` Solution :`T_(AV)=1.443, T_(50)=1.443xx100` MIN = 1443 min After ONE `T_(av)` CONCENTRATION of the reactant left is 1/e of the original concentration.
