The combustion of one mole of benzene takes place at 298K and 1 atm. After combustion, CO₂(g) and H₂O(l) are produced and 3267.0 kJ of heat is liberated. Calculate the standard enthalpy of formation of ∆_fH° benzene, given that standard enthalpy of formation of CO₂(g) and H₂O(l) are –393.5 kJ mol^–1 and –285.83 kJ mol^–1respectively.
