... Furthermore, the reaction rate is unaffected by ionic strength since the rate determining reaction is taking place between charged and uncharged species. Thus values of 104kobsof [4.49±0.05, 3.19±0.04, 3.84± 0.06 and3.37±0.03] s-1 are obtained at I= 0.2, 0.3, 0.4 and 0.5 mol dm-3 at pH=6.31, tempera ...

Electrochemistry
Electrochemistry is the branch of physical chemistry that studies chemical reactions which take place at the interface of an electrode, usually a solid metal or a semiconductor, and an ionic conductor, the electrolyte. These reactions involve electric charges moving between the electrodes and the electrolyte (or ionic species in a solution). Thus electrochemistry deals with the interaction between electrical energy and chemical change.When a chemical reaction is caused by an externally supplied current, as in electrolysis, or if an electric current is produced by a spontaneous chemical reaction as in a battery, it is called an electrochemical reaction. Chemical reactions where electrons are transferred directly between molecules and/or atoms are called oxidation-reduction or (redox) reactions. In general, electrochemistry describes the overall reactions when individual redox reactions are separate but connected by an external electric circuit and an intervening electrolyte.
