Calculating standard free energy change
WebKey Points. The standard free energy of a substance represents the free energy change associated with the formation of the substance from the elements in their most stable forms as they exist under standard conditions. Combine the standard enthalpy of formation and the standard entropy of a substance to get its standard free energy of formation.
