What is the significance of equilibrium constant?
(i) The numerical value of equilibrium constant is a measure of the extent to which reactants have been converted into the products. A large value of K indicates that reactants have been converted to the products to a large extent. The lower value of K indicates that only small amounts of reactants have been converted into products.
(ii) If we know the initial concentration of reactants and equilibrium constant of the reaction, we can calculate the equilibrium concentration of various reactants and products.
