Cells at Non-standard Conditions
- Standard Reduction Potentials allow prediction of
direction of spontaneous reaction
If Eo > 0 reaction proceeds to RIGHT (products)
If Eo < 0 reaction proceeds to LEFT (reactants)
- Eo only applies to [ ] = 1 M for all aqueous species
- at other concentrations, the cell potential differs
- Ecell can be predicted by Nernst equation
