Concept Introduction:
Equilibrium constant: Ratio of concentration of the products to the respective molar concentration of reactants gives the equilibrium constant (K) of a reaction. If the K value is less than one the reaction will move to the left side and the K values is higher (or) greater than one the reaction will move to the right side of reaction.
