According to Schwabe and Wagner, the enthalpies of combustion in a constant-volume calorimeter forfumaric acid (HO2CCH=CHCO2H) and maleic acid (HO2CCH=CHCO2H) are ?-1337.21 kJ mol-1 and?-1360.43 kJ mol-1, respectively, at approximately 25. a. Calculate the enthalpies of formation of these isomers. b. What is the difference in enthalpy between these isomers? Maleic acid is the cis-isomer of butenedioic acid, whereas fumaric acid is the transisomer.
