1)For the reaction Cu(s) + 2 Fe3+(aq) <-> Cu2+(aq) + 2 Fe2+(aq), the equilibrium constant is Kc = 3.7×10^14 at 25 oC. Suppose that excess Cu(s) is added to 1.0 L of 0.015 mol L^-1 Fe(NO3)3(aq), with no change in volume. What is the equilibrium concentration of Fe3+? Justify any approximations you make.
