Calculate the potential of the cell. Indicate whether the reaction will proceed spontaneously in the direction considered (oxidation on the left, reduction on the right) or an external voltage source is needed to force this reaction to occur. Indicate which electrode would be the cathode if the cell would be short circuited.
