A voltaic cell is constructed that uses the following half-cell reactions.
Cu+(aq) + e- Cu(s)
I2(s) + 2 e- 2 I -(aq)
The cell is operated at 298 K with [Cu+ ] = 2.3 M and [I - ] = 3.3 M.
(a) Determine E for the cell at these concentrations.
(b) If [Cu+ ] were equal to 1.0 M, at what concentration of I - would the cell have zero potential?

What values are you using for Eo for I2 and Eo for Cu^+ ==> Cu
My values are so old they may not agree with yours from a more modern text.
