  • According to the law of chemical equilibrium, the rates of the forward and reverse reactions are balanced at equilibrium.

Examples

  • The law of chemical equilibrium explains why the concentrations of reactants and products remain constant in a closed system.

Morphology

law + of + chemical + equilibrium

The phrase follows a fully compositional pattern 'law of X' so a learner who knows 'law', 'chemical', and 'equilibrium' will understand it denotes a scientific principle concerning chemical equilibrium. While the precise technical formulation (ratios of forward/reverse reaction rates) is specialist knowledge, the core meaning is directly derivable from the constituents and cross-linguistically transparent.

Etymology

Law of chemical equilibrium can be pictured as a busy door where people go in and out at the same speed: there is movement both ways, but the number of people inside stays the same. The 'law' means a rule and 'equilibrium' means balance, so the forward and reverse moves in a chemical reaction happen at steady rates and the amounts of reactants and products stay constant.
