The standard heat of formation (Delta_(f)H_(298)^(0)) of ethane (in kJ/mol), if the heat of combustion of ethane, hydrogen and graphite are -1560, -393.5 and -286kJ/mol , respectively is _______.

Calculate the resonance enegry of isoprene (C_(5)H_(8)) from the data given. Standard Heats of combustion of isoprene, carbon and hydrogen are -3186, -393.5 , and -285.83 kJ mol^(-1) , respectively. Bond energies of C=C, C-C, C-H and H-H bonds are 615, 348, 413 and 435.8 kJ mol^(-1) respectively. Standard heat of sulbilmation of graphite is 718.3 kJ mol^(-1) .

Calculate the enthalpy of formation of methane given that the enthalpies of combustion of methane, graphite and hydrogen are 890.2 KJ, 393.4 KJ and 285.7 KJ mol^(-1) respectively

The combusition of 1 mol of benzene (C_(6) H_(6)) takes place at 298 K and 1 bar pressure. After combustion, CO_(2) (g) and H_(2) O (1) are produced and 3267 kJ of heat is liberated. Calculate the standard enthaply of formation, Delta_(f) H^(@) of benzene. Standard enthapies of formation of CO_(2) (g) and H_(2) O (1) are - 393.5 kJ mol^(-1) and - 258.83 kJ mol^(-1) , respectively. Strategy : Apply Eq. the mathematical form of Hesis's law, to the combustion reaction of 1 mol of benzene. Remember Delta_(f) H^(@) for O_(2) (g) is zero by convention. We are give Delta_(1) H^(@) and Delta_(f) H^(@) values for all substance except C_(6) H_(6) (1) . We can solve for this unknown.
