Question

explain equilibrium state?

Answer 1

a state of balance between opposing forces or actions that is either static (as in a body acted on by forces whose resultant is zero) or dynamic (as in a reversible chemical reaction when the velocities in both directions are equal)

Answer 2

The chemical equilibrium state describes concentrations of reactants and products in a reaction taking place in a closed system,which no longer change with time. ... Equilibrium is denoted in a chemical equation by the ⇌ symbol.
