An electrochemical cell consists of a silver metal electrode immersed in a solution with [Ag⁺] = 1.00 M separated by a porous disk from a compartment with a copper metal electrode immersed in a solution of 10.00 M NH₃ that also contains 2.4 × 10^-3 M Cu(NH₃)₄²⁺. The equilibrium between Cu²⁺ and NH₃ is:

Assuming Ag⁺ is reduced, what is the cell potential at 25°C?
