Reaction coordinate diagrams for exergonic and endergonic reactions. In the exergonic reaction, the reactants are at a higher free energy level than the products (reaction goes energetically downhill). In the endergonic reaction reaction, the reactants are at a lower free energy level than the products (reaction goes energetically uphill). 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.
