Gibbs free energy and spontaneity. When a process occurs at constant temperature and pressure , we can rearrange the second law of thermodynamics and define a new quantity known as Gibbs free energy: where is enthalpy, is temperature (in kelvin, ), and is the entropy. Gibbs free energy is represented using the symbol and typically has units of .

Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy. Reactions with a positive ∆ G (∆ G > 0), on the other hand, require an input of energy and are called endergonic reactions. In this case, the products, or final state, have more free energy than the reactants, or initial state.

Throughout this topic I shall use the word "feasible", but if your examiners expect you to use the word "spontaneous", that is what you should do. Feasible changes and ΔG. I am dropping the "standard" symbol after ΔG from now on, because most of the time we shall be using it at non-standard temperatures.

A G vs. extent-of-reaction diagram for a non-spontaneous reaction can be interpreted in a similar way; the equilibrium composition will correspond to an extent of reaction greater than zero but less than 0.5. In this case, the minimum at reflects the increase in entropy when the reactants are "contaminated" by a small quantity of products.
