Question
6. Calculate the formation enthalpy (4H orm) for benzene (CsH6). Is this reaction endothermic or exothermic?
2C,H, + 150, - 12C02 + 6H,0
AH° = -6535 kJ
AH orm values: O;: 0 kJ/mol - CO;: –393.5 kJ/mol - H;O: -285.8 kJ/mol
MH = 1 g/mol, Mc = 12 g/mol, Mo = 16 g/mol, R = 0.08206 L.atm/mol.K or 8.314 J/mol.K
