Standard electrode potential
The standard electrode potential (abbreviated E0) is the electrode potential at the standard conditions: temperature 298K, 1 atm pressure and at 1 mol of the activity of redox participants of the half-reaction.
The standard electode potentials are listed in the table of standard electrode potentials.
Standard electrode potential and Gibbs free energy are related by the equation
where
- n is the number of moles of electrons per mole of products
- F is the Faraday constant, ~96 485 C/mol
Standard electrode potentials can be obtained by:
1) experimentally measured electrode potentials and corresponding recalculations by the Nernst equation (only for reversible reaction);
2) calculated from the Gibbs free energy of the half-reaction.
