Question
6. (a) An alternative to the lead/acid battery currently in use in automobiles is the
rechargeable Sodium/Sulfur battery. The sodium anode is separated from the sulfur
cathode by a -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.
(b) What is ∆G° for this process?
(c) Calculate Keq for this battery.
(d) What is the cell voltage is [S2–] = 0.15 M and [Na+] = 0.0125 M?
