The Nernst Equation and Gibbs Energy
How cell potential changes with concentration, and its link to spontaneity.
Nernst Equation
The Nernst equation relates the electrode potential of a cell to the concentrations (or activities) of the species involved, allowing calculation of EMF under non-standard conditions.
Relation to Gibbs Energy
ΔG = -nFEcell
The Gibbs energy change of a cell reaction is directly related to its EMF, connecting electrochemistry to thermodynamics.
