In the presence of oxygen, the cathode half-reaction writ- ten in the preceding problem is replaced by O: (8) + 2 H;O* (aq) + 2 e¯ → 3 H20(t) but the anode half-reaction is unchanged. Calculate the standard cell potential for this pair of reactions operating as a galvanic cell. Is the overall reaction spontaneous under standard conditions? As the water becomes more acidic, does the driving force for the rusting of iron increase or decrease?
