ScienceChemistryChemistry & Chemical ReactivityThe value for Δ f G ° for MX n for the reaction to be product favored at equilibrium is to be stated. Concept introduction: The change of Gibbs free energy to form one mole of a substance from its constituent elements when all the substances in the standard form is known as standard Gibbs free energy of formation ( Δ f G ° ) . The standard Gibbs free energy of reaction ( Δ r G ∘ ) in terms of standard Gibbs free energy of formation ( Δ f G ° ) is written as, Δ r G ∘ = ∑ Δ f G ∘ products − ∑ Δ f G ∘ reactants If the value of standard Gibbs free energy of reaction ( Δ r G ∘ ) is positive then the reaction is reactant favored. If the value of standard Gibbs free energy of reaction ( Δ r G ∘ ) is negative then the reaction is product favoured and spontaneous.
