28. The following equation represents the combustion of benzene, C6H6(1) C6H6(1) +15/202 (g) 6CO2 (g) + 3H2O (1) The standard enthalpy of combustion of benzene is -3273 kJ/mol; if the enthalpies of formation of CO2 (g) and H2O (1) are -393.5 kJ/mol and -241.8 kJ/mol respectively, calculate the enthalpy of formation of benzene.
