Problems for week 14 discussion 2. Each of the six cells in a lead-acid car battery delivers 2.00 V from the following redox reaction: Pb ( s ) + PbO 2 ( s ) + 2 H 2 SO 4 ( aq ) 2 PbSO 4 ( s ) + 2 H 2 O Write out the balanced oxidation and reduction ½ reactions in order to determine how many e - are transferred in each cell, and then calculate G ° . 1. 3. Nuclear submarines can sustain their crew underwater for long periods by using electrolysis to produce the needed oxygen from water. If an electrolytic cell that draws 0.025 A of current is operated for 1 hr, how many moles of O 2 could be produced? A mole of an ideal gas at 298K and 1 atm occupies 22.4 L. How many liters of O 2 could be generated by the electrolysis cited above in the course of 1 hour? A voltaic cell employs the following redox reaction: 3 Fe 3+ ( aq ) + 2 Mg ( s ) 2 Fe ( s ) + 3 Mg 2+ ( aq ) Using ½ cell potentials from a reference table, calculate the cell potential at 25 ° C under the following conditions:
