Morphology

exoergic + reaction

The phrase is fully compositional: 'exoergic' means 'releases energy' and 'reaction' denotes a chemical/nuclear process, so together they mean 'a reaction that releases energy.' Although 'exoergic' is somewhat technical, its meaning is predictable from the constituent morpheme (similar to 'exothermic'), so a learner who knows both words would understand the MWE.

Etymology

Exoergic reaction comes from Greek parts exo meaning 'out' and erg meaning 'work', so it paints the picture of energy moving out of a system. Imagine a kettle giving off heat and steam; the energy leaves the kettle, so an exoergic reaction is a reaction that releases energy.
