Given The enthalpy of hydrogenation of these compound will be in

If the enthalpy of combustion of benzene (l), carbon (s) and hydrogen (g)are Q_(1) Q_(2)and Q_(3) respectively, what will be enthalpy of formation of Benzene?

The enthalpy of combustion at 25^(@)C of H_(2)(g) , cyclohexane and cyclohexene are -241, 3920 and -3717 kJ "mole"^(-1) respectively. The heat of hydrogenation of cyclohexene is ( Kcal/mole) approximate integer:

The standard molar enthalpies of formation of cyclohexane (l) and benzene (l) at 25^@C are - 156 and +49 KJ mol^(-1) respectively. The standard enthalpy of hydrogenation of cyclo hexene (l) at 25^@C " is" -116 "KJ mol" ^(-1) . Use these data to estimate the magnitude of the resonance energy of benzene.
