Calculate the equilibrium constant for the reaction that occurs when a copper electrode is placed in a solution of 0.1 M copper(II) sulfate and connected to a standard hydrogen electrode. The cell potential at standard conditions is observed to be 0.34 V. (Hint: Use the Nernst equation to relate the cell potential to the equilibrium constant.)
