$0.1\mathrm{M}\mathrm{ }\stackrel{{\mathrm{t}}_{1/2}}{\to }0.05\mathrm{M}\mathrm{ }\stackrel{{\mathrm{t}}_{1/2}}{\to }0.025\mathrm{M}$
$\begin{array}{l}{\text{for the I}}^{\text{st}}\text{ order reaction :-}\\ \\ {\text{t}}_{3/4}=2\times {\text{t}}_{1/2}=2\times 15=30\text{ minute}\end{array}$
successive half lives in first order reactions remain constant irrespective of initial concentration.
