Capstone: Full Electrochemical Profile of a Galvanic Cell
Captions available
The idea
This capstone carries one galvanic cell through its full electrochemical profile — standard cell potential, standard free energy change, equilibrium constant, and Nernst-adjusted potential under stated nonstandard conditions — showing all four are one relationship read four ways.
Where people slip
Reporting a Nernst-adjusted Ecell as though it were a new standard cell potential, rather than the same cell's potential under the one nonstandard condition actually stated, discards the distinction Chem 2196 draws between E°cell and Ecell.
