The mineral that has the lowest free energy at the point where the three phases intersect has to be given. Concept introduction: Chemical equilibrium : The term applied to reversible chemical reactions. It is the point at which the rate of the forward reaction is equal to the rate of the reverse reaction. The equilibrium is achieved; the concentrations of reactant and products become constant. Free energy change ΔG 0 : change in the free energy takes place while reactants convert to product where both are in standard state.

Definition Definition State where the components involved in a reversible reaction, namely reactants and product, do not change concentration any further with time. Chemical equilibrium results when the rate of the forward reaction becomes equal to the rate of the reverse reaction.
