Definition

An 'exergonic' reaction is a chemical reaction where energy is released into the surroundings. Think of it like burning wood – it releases heat and light πŸ”₯. The energy released is usually in the form of heat or light. The products of the reaction have less energy than the reactants. In simpler terms, it's like a downhill process that gives off energy. It’s the opposite of endergonic.

Etymology

The word 'exergonic' is derived from the Greek prefix 'exo-' meaning 'out' or 'outside', and 'ergon' meaning 'work' or 'energy'. It combines these to describe a process where energy exits the system. The term was coined in the 20th century to describe chemical reactions that release free energy.
