In a liquid-phase reaction, ethanol and acetic acid react to form ethyl acetate and water. The following thermochemical formation data in the liquid phase at 25◦C is available: Spec. ∆fH◦ (kJ/mol) ∆fG◦ (kJ/mol) Ethanol -234.95 -167.85 Acetic acid -432.80 -374.60 Ethyl acetate -444.50 -328.00 Water -241.82 -228.57 (a) By hand, compute the equilibrium concentration at 80◦C from an initially equimolar mixture of ethanol and acetic acid, assuming the liquid mixture is an ideal solution. You may assume ∆rxnH◦ is independent of temperature. (b) Repeat the calculation of part (a), except with a feed that has a 3:1 molar ratio of ethanol to acetic acid.
