Illustrate with an example what is meant by standard free energy change of formation of compound State the relation between standard free energy change and equilibrium constant of a chemical reaction.
Standard free energy of formation is the free energy change that occurs when 1 mole of a compound forms from its component elements at standard conditions.
The standard change in free energy, ΔG, for a reaction is related to its equilibrium constant, K, by the equation ΔG = -RTlnK.
