Using the technique of the previous problem ?E was found to be -2,000.00 kJ/mol at 298 K for an unknown liquid hydrocarbon. In another experiment it was determined that for each mole of hydrocarbon, 1.6 moles of oxygen gas are consumed and 7 moles of CO2 gas and 5 moles of H2O liquid are produced. Find ?H per mole of this hydrocarbon (in kJ) at 298 K.
