Morphology
The noun phrase combines 'chemical' (relating to chemistry) with 'reaction' (a process or response), so its meaning — a process in which chemicals change — is directly compositional and derivable from the parts. This modifier+noun pattern is common cross-linguistically (e.g. reacción química, réaction chimique), so a B1 learner who knows both words will grasp the MWE.
Etymology
Chemical reaction gives a simple picture: a chemical is a substance and a reaction is what happens when things meet and change. Imagine two liquids mixing and making a new gas or a new colour—this image shows why it means 'a process where one substance changes into a different substance'.
