exergonic reaction (exoergic reaction)

https://doi.org/10.1351/goldbook.E02262
This expression is often applied to a reaction for which the overall standard Gibbs energy change \(\Delta G^{\,\unicode{x26ac}}\) is negative. Some workers use this term with reference to a negative value of \(\Delta H^{\,\unicode{x26ac}}\) at the absolute zero of temperature.
