Question
When alcohol (C2H5OH (l)) and acetic acid (CH3COOH (l)) are mixed together in equimolar ratio at 27oC , 33% of each is converted into ester. Then the KC for the equilibrium
C2H5OH(l) + CH3COOH (l) ⇋ CH3COOC2H5 (l) + H2O(l).
C2H5OH(l) + CH3COOH (l) ⇋ CH3COOC2H5 (l) + H2O(l).
Options
A.4
B.1/4
C.9
D.1/9
Solution
C2H5OH (l) + CH3COOH (l) ⇋ CH3COOC2H5 (l) + H2O (l).
