![Enthalpy H is a measure of the energy content of a
system at constant pressure. Chemical reactions
involve changes in enthalpy, AH, which can be
measured and calculated:
ΔΗ,xn° = Σproducts mΔΗ;° - Σreactants nΔΗ,°
where the subscript "rxn" is for "enthalpy of reaction"
and "f" is for "enthalpy of formation" and m and n
represent the appropriate stoichiometric coefficients for
each substance.
The following table lists some enthalpy of formation
values for selected substances.
