Why is the equilibrium constant independent of concentration? 
I think it should be dependent on the concentration as the formula for finding the equilibrium constant is according to this photo 
The bold letters show the formula and it clearly show it's dependency on concentration then why do say K is independent of concentration ? Please explain elaborately.

Expert Answer:

As  product  concentration increases, the rate of the reverse reaction increases. Eventually they reach the point where the rate that reactants are converted into products exactly equals the rate that products are converted  into  reactants.  This  is  equilibrium  and  the  concentrations  of  reactants  and  products do not change. Because of this equilibrium constant do not change with the change in concntration.
