PREVIOUS APPROACHES TO BOND BREAKING ELECTROCHEMICAL REACTIONS [Pg.34]

The first approaches towards a theoiy for electrochemical reactions in which bonds are broken were given independently by German and Kuznetsov and Saveant for reactions such as [Pg.34]

A simple model based on a Morse curve description of the potential energy surface for bond-breaking (see Fig. 5) has been proposed [Pg.34]

The first equation represents the situation before, while the second one describes the behaviour after the bond breaking. A is the dissociation energy of the RX bond. This leads to a quadratic activation driving force free energy relationship [Pg.34]

If the system is under equilibrium conditions, the overpotential rj is zero and the standard activation free energy becomes the snm of two contributions characterizing bond-breaking (D and solvent reorganization (A), respectively [Pg.35]
