The esterification reaction of acetic acid with ethanol to give ethyl acetate proceeds with the following stoichiometry: CH3COOH + C2H5OH ----> H20 + CH3COOC2H5. using standard thermochemical data evaluate the enthalpy change associated with this reaction at 298 K,next evaluate the enthalpy change at 750 K and pressure of 1.00 bar. (the formation enthalpy and molar heat capacity of ethyl acetate are -479 KJ/mol and 170.1 J/(mol*k)
