A state in a chemical reaction when the forward and backward reactions happen at the same speed

is the same meaning but uses an explicit chemistry qualifier in the name

Morphology

chemical + equilibrium

The meaning is directly derivable from combining 'chemical' (relating to chemistry or chemical processes) with 'equilibrium' (a balanced or steady state), so a learner who knows both constituents can infer it refers to a balanced state in a chemical reaction. This is a regular noun-modifier composition found across languages and follows standard English formation, making it immediately comprehensible to B1 learners.

Etymology

Chemical equilibrium paints a picture of a doorway where as many people go in as go out. That image explains it: equilibrium means balance and chemical shows it happens in a reaction, so the forward and backward steps happen at the same speed and the amounts of the chemicals 'stay the same'.
