| Abstract: | The emf of an electrochemical cell is interpreted by use of measurable local changes in Gibbs energy across the cell. It is shown by calculation that the contribution to emf from changes in electrostatic potentials is negligible for most conditions. The contribution is in principle measurable. This way of explaining contributions to emf is compared to the traditional interpretation in terms of sums of electrostatic potentials. |
