Morphology
The phrase is fully compositional: 'exothermic' denotes producing or releasing heat and 'reaction' denotes a chemical process, so together they straightforwardly mean a chemical reaction that releases heat. This adjective+noun pattern is a standard, predictable combination (and has direct cognates in many languages), so a B1 learner who knows both constituents can infer the MWE meaning.
Etymology
The term exothermic reaction comes from Greek parts: exo- meaning 'out' and -thermic meaning 'heat'. So it paints the image of heat moving 'out' from the reaction into the surroundings, which is why it means a reaction that 'releases heat'.
