Characteristics of Equilibrium constant:-

• Equilibrium constant is applicable only when concentration of reaction & product have attained their equilibrium state.
• The value of equilibrium constant is independent of the original concentration of the reactant.
• The equilibrium constant has a definite value for every reaction at a particular temperature.
• For a reversible reaction, the equilibrium constant for the forward reaction is inverse of the equilibrium constant for the backward reaction.                                   
• The value of equilibrium constant tells us the extent to which reaction proceed in the forward or the reverse direction.

K less = Product less or vice versa

• Equilibrium constant is independent on the presence of catalyst.
