Standard Thermodynamic Properties of Chemical Substances

Notes

• Δ_fH° is the standard molar enthalpy (heat) of formation at 298.15 K in kJ mol^–1
• Δ_fG° is the standard molar Gibbs energy of formation at 298.15 K in kJ mol^–1
• S° is the standard molar entropy at 298.15 K in J mol^–1 K^–1
• C_p is the molar heat capacity at constant pressure at 298.15 K in J mol^–1 K^–1

The standard state pressure, p°, is 1 bar (or 10⁵ Pa).

States of matter are indicated as solid/crystalline (c), liquid (l), and gas (g).

A reference state of an element is indicated with a standard molar heat of formation, Δ_fH°, of 0.
