Principle
The standard molar enthalpies of formation
ΔBHΦ are important compiled thermodynamic
tabulation quantities for calculating standard enthalpies of
reaction for any arbitrary reaction. They are defined as the heat
of reaction occurring in the direct formation of one mole of the
pertinet pure substance from the stable pure elements at constant
pressure. For spontaneous and quantitative formation reactions,
e.g. the conversion of carbon and oxygen to CO2,
standard enthalpies of formation can be measured directly using
calorimetry. Alternativly, they can be calculated from known
entahlpies of reaction using Hess's law.
Benefits
