The Equilibrium Constant Kc

The equilibrium constant Kc is a measure of the relative concentrations of products and reactants in the equilibrium system.The equilibrium law allows the calculation of the exact position of equilibrium. An expression for the equilibrium constant for any reversible reaction:For example:
