To determine the value of Kc for the reaction. CH3COOH + C2H5OH CH3COOC2H5 + H2O 1 mole of CH3COOH and 1 mole of C2H5OH in 1dm3 of solution in an inert solvent containing a small amount of acid catalyst were warmed until no further change occurred. At equilibrium, 0.667 mole of water was present. Calculate the value of Kc?
