Vedclass · Answer

(C) The half-life period $(T_{1/2})$ is defined as the time required for the concentration of a reactant to be reduced to half of its initial value.After one half-life period,the amount of substance remaining is given by the formula $N = N_0 	imes (1/2)^n$,where $n$ is the number of half-lives.For $n = 1$,$N = N_0 	imes (1/2)^1 = N_0/2$.Therefore,after one half-life,$1/2$ of the initial substance is left.

$A$ substance of which $1 \ g$ is taken,after one half-life period,what fraction of it is left?
