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 Σ μιoducts mΔΗ -Σctants nΔΗ; ο
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.
Substance
AH;° (kJ/mol)
CO2 (g)
-393.5
NaOH(s)
-426.7
H2O(1)
-285.8
NażCO3 (s)
-1131.0
H2O(g)
-241.8
