Morphology
chemical + decomposition + reaction
The phrase is fully compositional: 'chemical' (relating to chemistry) + 'decomposition' (breaking down into simpler parts) + 'reaction' (a chemical process) directly yield the meaning of a reaction in which a compound breaks down into other substances. This transparent composition follows standard scientific naming patterns and would be understandable to a learner who already knows the constituent words.
Etymology
Chemical decomposition reaction gives a simple picture: a single chemical goes through decomposition during a reaction, like a toy falling into pieces. So it means one compound 'breaks down' into 'two or more substances'.
