Solution

For first order reaction $\mathrm{t}_{1 / 2}=\frac{\ell \mathrm{n} 2}{\mathrm{k}}$

For first order reaction
$\begin{aligned}
& \log \frac{[R]_0}{[R]}=\frac{1}{2.303} \mathrm{kt} \\
& \log \frac{[\mathrm{R}]_0}{[\mathrm{R}]}=\left(\frac{\mathrm{k}}{2.303}\right) \times \mathrm{t}
\end{aligned}$
