Consider the reaction: Cu^2+ + 4NH3 ⇌ [Cu(NH3)4]^2+ If the initial concentration of Cu^2+ is 0.5 M and the initial concentration of NH3 is 2 M, what is the concentration of [Cu(NH3)4]^2+ at equilibrium if the concentration of NH3 is increased to 5 M? (Assume the volume of the solution remains constant and the temperature is kept constant.)
