Posted by Maho on Monday, March 17, 2014 at 11:39pm.

Using a table of standard electrode potentials (as in Appendix M of your text), calculate the standard cell potential, Eo, for: 2 Fe2+(aq) + Cl2(g) 2 Fe3+(aq) + 2 Cl(aq).

Answer:

Anode: 2 Fe2+ 2 Fe3+ + 2 e
Eox = 0.771 V
Cathode: Cl2 + 2 e 2 Cl Ered = +1.36 V
Enet = +0.59 V
