Question
  1. (a) An alternative to the lead/acid battery currently in use in automobiles is the rechargeable Sodium/Sulfur The sodium anode is separated from the sulfur cathode by a b-alumina porous cell.

 

Na+ + e ------> Na(s)                                 E°red = –2.71 V

S(s) + 2e ------> S2–                                     E°ox = + 0.48 V

Using the provided electrode potentials, calculate E°cell for this battery.

  • What is ∆G° for this process?
  • Calculate Keq for this
  • What is the cell voltage is [S2–] = 15 M and [Na+] = 0.0125 M?
