Question

what is a chemical equilibrium and how is it exist

Answer 1

chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time.[1] Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction

Answer 2

Answer:

Chemical equilibrium : It is defined as the state of a reversible chemical reaction at which the rates of forward and reverse reactions are equal and the concentrations of the reactants and the products have constant values. When there is no further change in concentration of reactant and product, we say that the reaction has attained equilibrium, with the rates of forward and reverse reactions being equal.
