Q. For a pseudo first order reaction,
$CH_{3}COOC_{2}H_{5}+H_{2}O\xrightleftharpoons{H^{+} } CH_{3}COOH+C_{2}H_{5}OH$ the net rate is given by
$\frac{d x}{d t}=4\times10^{-4} L mol^{-1} s^{-1} \left[\left(CH_{3}COOC_{2}H_{5}\right)\right]-3\times10^{4}L \, mol^{-1} s^{-1}\left[CH_{3}COOH\right]\left[C_{2}H_{5}OH\right]$
Then, the equilibrium constant of the reaction would be

Solution:

Correct answer is (d) $1.33\times10^{-8} mol \, L^{-1}$
