For cell, Zn|ZnSO4(0.01 M)||CuSO4(1.0 M)|Cu, calculate Ecell.

1. Ecell = E°cell - 2.303RT/nF log [Zn^2+]/[Cu^2+]
2. Ecell = E°cell - 2.303RT/nF log 1/0.01
3. Ecell = E°cell - 2 × F × log 1/0.01
4. None of the above

Correct answer: Ecell = E°cell - 2.303RT/nF log [Zn^2+]/[Cu^2+]

Solution

The Nernst equation is used to calculate the cell potential under non-standard conditions. The correct formula is Ecell = E°cell - (2.303RT/nF) log([Zn²⁺]/[Cu²⁺]).
