Propane (C3H8) is a possible alternative automobile fuel with a density of 4.0 lb/gal and a standard enthalpy value Hº = -104.2 kJ/mol. Find its higher heating value (HHV) and net heat of combustion (LHV) in kJ/mol and in Btu/gal.
P6.36 We need to calculate a standard-state AĦ", for the oxidation of p-xylene (CH1,) to terephthalic acid (TPA, C,O̟H), which is used in making plastic 2-L soda bottles. However, heats of formation of the compounds from the respective elements are not available. Reference tables do have information on heats for combustion to CO, (g) and H,O (1) at 25°C, and show that the energy released is 1089 kcal/mol for p-xylene (1) and 770 kcal/mol for TPA (s).

A sample of biphenyl (C6H5)2 weighing 0.526 g was ignited in a bomb calorimeter initially at 25°C, producing a temperature rise of 1.9K. In a separate calibration experiment, a sample of benzoic acid C6H5COOH weighing 0.825 g was ignited under identical conditions and produced the same temperature rise of 1.9K. For benzoic acid, the heat of combustion at constant pressure is known to be 3226 kJ mol–1 (that is, ΔU = –3226 kJ mol–1.). Temperature was measured with ±0.1K accuracy Use this information to determine the standard enthalpy of combustion of biphenyl with error of the calculated enthalpy of biphenyl combustion
