In an experiment starting with `1` mol `C_(2)H_(5)OH, 1` mol `CH_(3)COOH`, and `1` mol of water, the equilibrium mixture mixture of analysis showa that `54.3%` of the acid is eaterified. Calculate `K_(c)`.

Text Solution

Verified by Experts

The correct Answer is:
`K_(c)= 4.012`
The degree of dissociation `(alpha) =54.3% =0.543`
`{:(,C_(2)H_(5)OH,+,CH_(3)COOH,hArr,CH_(3)COOC_(2)H_(5),+,H_(2)O),("Initital molar conc.",1,,1,,0,,1),("Equilibrium molar conc.",1-0.543,,1-0.543,,0.543,,1),(,=0.457,,=0.457,,0.543,,=1.543):}`
`K_(c) =[[CH_(3)COOC_(2)H_(5)][H_(2)O]]/[[C_(2)H_(5)OH][CH_(3)COOH]] =(0.543xx 1.543)/(0.457xx0.457)= 4.012`
