Acid catalysed hydrolysis of \( \mathrm{CH}_{3} \mathrm{COOC}_{2} \mathrm{H}_{5} \) is monitored by taking equal amount of solution after certain interval of time and titrating it with \( \mathrm{NaOH} \). Following data were obtained.
P
\[
\text { Rate }=\mathrm{K}\left[\mathrm{H}^{+}\right]\left[\mathrm{CH}_{3} \mathrm{COOC}_{2} \mathrm{H}_{5}\right]
\]
W
\begin{tabular}{|c|c|c|c|}
\hline Time(min) & 0 & 20 & \( \infty \) \\
\hline Volume of \( \mathrm{NaOH}(\mathrm{in} \mathrm{ml}) \) & 20 & 80 & 100 \\
\hline
\end{tabular}
- If \( \left[\mathrm{H}^{+}\right]=0.7 \mathrm{M} \). Find ' \( \mathrm{K}^{\prime} \) in \( \mathrm{M}^{-1} \mathrm{~s}^{-1} \). [Take \( \left.: \ln 2=0.7\right] \)
