A Voltaic cell is made from lead and manganese at standard state conditions. What happens to the lead and manganese electrodes over time? current Mn Anode Pb Cathode Reduction half-reaction Pb2+ (aq) + 2e → Pb(s) -0.13 V Mn2+(aq) + 2e → Mn(s) -1.18 V A) Nothing, this cell would not have spontaneous electron flow. B) The lead electrode would shrink over time and the manganese electrode would grow. C) The manganese electrode would shrink over time and the lead electrode would grow. D) Both electrodes would get larger over time. E) Both electrodes would shrink over time. What is the voltage developed by the battery pictured above? A) 1.31 V B) -1.31 V C) 1.05 V D) -1.05 V E) cannot be determined In the cell above, if the concentration of Mn 2+ (aq) is increased in the right chamber, the voltage will: A) increase B) decrease C) remain the same, but the battery will last longer D) the voltage will not be affected, nor will the life of the battery
