On the basis of the remaining results, this deviation likely stems from either the boiling point calculation or the assumed enthalpy of fusion as the gas phase enthalpy of formation is generally within 2–3 kcal/mol of the experimental value and the combustion product energies are unlikely to ...
pressure summation based on the Virial equation. Consequently, the results showed that the calculation method on the basis of the Dalton's law of pressure summation appears to be a reasonable enthalpy values for the 6MPa oxygen-enriched coal combustion as opposed to the inferior cofunction method....
Δh f enthalpy of combustion – it is the change in enthalpy accomplished when one mole of an element is heated in the presence of excess oxygen under standard conditions. it is denoted as Δh c . enthalpy of the solution – it is defined as the total amount of heat released or ...
