An energy profile is a diagram representing the energy changes that take place during a chemical reaction. Enthalpy change, ΔH, is the amount of energy absorbed or released by a chemical reaction. On an energy profile, the enthalpy change for the reaction is measured from the energy of the reactants to the energy of the products.

Reactions are classified as either exothermic (H < 0) or endothermic (H > 0) on the basis of whether they give off or absorb heat. Reactions can also be classified as exergonic (G < 0) or endergonic (G > 0) on the basis of whether the free energy of the system decreases or increases during the reaction.. When a reaction is favored by both enthalpy (H o < 0) and entropy (S o > 0), there is no ...

The diagram below is called a reaction coordinate diagram. It shows how the energy of the system changes during a chemical reaction. In this example, B is at a lower total energy than A. This is an exothermic reaction (heat is given off) and should be favorable from an energy standpoint.

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.
