Chemistry Question on Chemical Kinetics

For a pseudo first order reaction, CH3COOC2H5+H2OCH_{3}COOC_{2}H_{5}+H_{2}O <=>[H+] { <=>[H^{+}] } CH3COOH+C2H5OHCH_{3}COOH+C_{2}H_{5}OH the net rate is given by dxdt=4×10−4Lmol−1s−1[(CH3COOC2H5)]−3×104L mol−1s−1[CH3COOH][C2H5OH]\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

A

1.3×10−7mol L−1s−11.3\times10^{-7} mol \, L^{-1} s^{-1}

B

1.3×10−6mol L−1s−11.3\times10^{-6 }mol \, L^{-1} s^{-1}

C

1.33×10−9mol L−11.33\times10^{-9} mol \, L^{-1}

D

1.33×10−8mol L−11.33\times10^{-8} mol \, L^{-1}

Answer
