Key Concepts

Exergonic Reaction

Exergonic reactions are processes that release energy, characterized by a negative change in Gibbs free energy. This indicates that the products are at a lower energy state than the reactants, making these reactions thermodynamically favorable and spontaneous under constant temperature and pressure.

Gibbs Free Energy

Gibbs free energy is a thermodynamic quantity used to predict whether a process or reaction will occur spontaneously. A negative change in Gibbs free energy (?G < 0) means the reaction can proceed without additional energy input, as it indicates that the products are energetically more stable than the reactants.
