Kotz and Triechel, Chemistry and Chemical Reactivity Chapter XX: Sections xx.
- 19.4 The electrochemical potential of a voltaic cell is the difference in potential energy required to move electrons from electrode to the other along the connecting circuit. Half-cell potentials are measured at standard temperature and pressure for 1.0 Molar solutions (liquids) or 1.0 bar solutions (gases). Once we know the standard potentials for a half-reaction, we can predict the net change in electrical potential for combinations of half-cells, and the direction of electron flow.
