When ethanol and acetic acid are mixed together in equimolar proportions, equilibrium is attained when `2//3rd` of acid and alcohol are consumed. The equilibrium constant for the reaction is

Options

A. 0.4
B. 40
C. `4xx10^(2)`
D. `4xx10^(@)`

Answer

D

Explanation

`{:(CH_(3)COOH,+,C_(2)H_(5)OH,hArr,CH_(3)COOC_(2)H_(5),+,H_(2)O),(1 "mol",,1"mol",,-,,-),(1//3"mol",,1//3"mol",,2//3"mol",,2//3"mol"):}`
`K=(2//3xx2//3)/(1//3xx1//3)=4`
