• # question_answer What qualitative information can you obtain from the magnitude of equilibrium constant?

(i) Large value of equilibrium constant $(>{{10}^{3}})$ shows that forward reaction is favoured, i,e., concentration of products is much larger than that of the reactants at equilibrium. (ii) Intermediate value of $K\,({{10}^{-3}}\,\text{to}\,{{10}^{3}})$ shows that the concentration of the reactants and products are comparable. (iii) Low value of $K(<{{10}^{-3}})$ shows that backward reaction is favoured, i.e., concentration of reactants is much larger than that of the products.
