2. (a) The heat of combustion of liquid benzaldehyde (C6H5CHO) is -3393 kJ/mole, and that of liquid 2,4,6-cycloheptatrien-1-one (C₂H6O) is -3470 kJ/mole. Assume that both combustions result in products, CO2 and H₂O, that are entirely in the gas phase. Using the standard chemical equation for the combustion of a hydrocarbon, find the heats of formation (in kJ/mol) for both benzaldehyde and 2,4,6-cycloheptatrien-1-one in the liquid phase. (b) Consider the isomerization from 2,4,6-cycloheptatrien-1-one to benzaldehyde. What is the enthalpy change (in kJ/mol) for this reaction? Is it endothermic or exothermic? (c) If ArxnS = -18 J/mol-K for the isomerization reaction, find ArxnG at 350 K (in kJ/mol) and determine if it is spontaneous in the liquid phase at this temperature. For this calculation, you may assume that ArxnH and ArxnS are constant between 300 and 350 K.
