Exergonic (/ɛksɜːrˈɡɒnɪk/) is a term used in Biochemistry and Thermodynamics to describe a process that releases energy during its progress. The term is derived from the Greek words "ex" meaning "out of" and "ergon" meaning "work".
Definition
An exergonic reaction refers to a chemical reaction where the change in the Free energy is negative, indicating a spontaneous reaction. In other words, the energy of the products is lower than the energy of the reactants. This energy difference is often released as heat, light, or sound.

- Gibbs free energy: A thermodynamic potential that measures the maximum reversible work that a system can perform at constant temperature and pressure.
- Enthalpy: A measure of the total energy of a thermodynamic system.
- Entropy: A measure of the randomness or disorder of a system.
