What fraction of a reactant remains unreacted after 40 min if `t_(1//2)` is of the reaction is 20 min? consider the reaction is first order

What fraction of a reactant showing first order remains after 40 minute if t_(1//2) is 20 minute ?

What fraction of a reactant showing first order remains after 40 minute if t_1//_2 is 20 minute ?

Calculating fraction : The rate constant of a first order reaction is 0.0231 min^(-1) . What fraction of the reactant remains after 70 minuts ? Strategy : If 'f' is the reaction of the reactant reacting after 70 minutes, then the fraction of the reactant remaining after 70 minutes will be 1 - f.

A first order reaction takes 40 min for 30% decompositon.

Half life of a first order reaction is 10 mins what is the % of reaction completed in 100 mins?
