BRAINCAKEChemical Equilibria
Equilibrium can only be reached in a closed system where the reactants andproducts cannot escape.
Equilibrium is a dynamic process but the macroscopic properties (e.g. concentrations) of the system do not change with time. Equilibrium can be approached in either direction.
