The equilibrium concentration of [ HgI 4 2 − ] has to be calculated. Concept introduction: Equilibrium concentration is defined as the state when reactants and products are present in concentrations which do not change with time. The equilibrium concentration occurs when the rate of forward reaction becomes equal to the rate of backward reaction.
