What qualitative information can be obtained from the magnitude of the equilibrium constant?
Large values of equilibrium constant (> 103) show that the forward direction is favored i.e. concentration of products is much larger than that of the reactants of equilibrium. Intermediate values of K (10-3 to 103) show that the concentrations of the reactants and products are comparable. The low value of K (< 10-3) shows that the backward reaction is favored, i.e., the concentration of reactants is much large than that of. products.
