Think of a generic redox pair: $$\ce{Ox + ne- -> Red}$$ and use Nernst equation (and a few simplifications) to calculate its potential: $$ E = E^\circ + \frac{\mathrm{RT}}{\mathrm{nF}}\mathrm{ln}\left …

If you think of the Nernst equation, you'll see that: $$\Delta G° = -nFE°$$ Since $n$ corresponds to the number of electrons transferred, the ratio $\frac{\Delta G°}{n}$ remains constant, because any …

Following on Derek's great answer, it is very important to remind that the conventional way we use to add half-cell potentials is a consequence of the conservation of energy. Therefore, we should look …

The resistance you'll find in your system basically corresponds to that of the solution (plus some charge-transfer resistance if your kinetics are somewhat sluggish). Remember that for current to cir …
