When alcohol `(C_(2)H_(5)OH(l)) "and acetic acid" (CH_(3)COOH(l))` are mixed together in equimolar ratio at `27^(@)C,33%` of each is converted into ester. Then the `K_(c)` for the equilibrium
`C_(2)H_(5)OH(l)+CH_(3)COOH(l)hArrCH_(3)COOC_(2)H_(5)(l)+H_(2)O(l)`is:

A

`4`

B

`1//4`

C

`9`

D

`1//9`

Text Solution

Verified by Experts

The correct Answer is:
B
`C_(2)H_(5)OH(l)+CH_(3)COOH(l)hArrCH_(3)COOC_(2)H_(5)(l)+H_(2)O(l)`.
`{:(a,a,0,0,),(a,0.33a,a-0.33a,0.33a,0.33a):}`
`K_(C)=((0.33a)xx(0.33a))/((0.67a)xx(0.67a))=K_(C)=1//4`
