The standard enthalpy of formation (ΔHf°) is the enthalpy change when one mole of a compound is formed from its elements in their standard states (1 atm, 25 °C). These values form the basis for calculating reaction enthalpies using Hess’s law. For instance, ΔHf° of CO2(g) is –393.5 kJ/mol. Compiling these data in tables enables quick assessment of reaction energetics.
