WebFree-energy diagrams, or reaction coordinate diagrams, are graphs showing the energy changes that occur during a chemical reaction. The reaction coordinate represented on the horizontal axis shows how far the reaction has progressed structurally. WebEntropy of reaction at standard conditions Data from NIST Standard Reference Database 69: NIST Chemistry WebBook The National Institute of Standards and Technology (NIST) uses its best efforts to deliver a high quality copy of the Database and to verify that the data contained therein have been selected on the basis of sound scientific judgment.

WebReactions that have a negative ∆ G release free energy and are called exergonic reactions. (Handy mnemonic: EXergonic means energy is EXiting the system.) A negative ∆ G means that the reactants, or initial state, have more free energy than the products, or final state. The change in Gibbs free energy, let me do this in another color.
