1.0 mole of ethyl alcohol and 1.0 mole of acctic acid are mixed. At equilibrium, 0.666 mole of ester is formed. The value of equilibrium constant is

A

`1//4`

B

`1//2`

C

4

D

3

Text Solution

Verified by Experts

The correct Answer is:
C
`C_(2)H_(5)OH+CH_(3)COOH harr CH_(3)COOC_(2)H_(5)+H_(2)O`

`K_(c)=([CH_(3)COOC_(2)H_(5)][H_(2)O])/([C_(2)H_(5)OH][CH_(3)COOH])`
`=(0.666 xx 0.666)/(0.333 xx 0.333)=4`
