Electron transfer (ET) occurs when an electron relocates from an atom, ion, or molecule, to another such chemical entity. ET describes the mechanism by which electrons are transferred in redox reactions.
Electron transfer reaction is a reaction in which a single electron is transferred from one molecule to another . For example, a reaction that occurs when steel wool (made of iron atoms) is placed in a solution of CuSO4 is given in Figure \(\PageIndex{1}\) below:
23 Αυγ 2021 · Electron transfers that occur via ligands shared by the two metals undergoing oxidation and reduction are termed "inner sphere" electron transfers. Taube was awarded the Nobel Prize in chemistry in 1983; the award was based on his work on the mechanism of electron transfer reactions.
10 Νοε 2022 · In this chapter, we have described various galvanic cells in which a spontaneous chemical reaction is used to generate electrical energy. In an electrolytic cell, however, the opposite process, called electrolysis, occurs: an external voltage is applied to drive a nonspontaneous reaction.
Electron transfers are frequently rather fast, compared with many reactions which undergo, instead, a breaking of chemical bonds and a forming of new ones. Accordingly, the study of a large body of fast electron transfer reactions became accessible with the introduc-tion of this instrumentation.
28 Οκτ 2019 · A central theme in introductory and advanced chemical education courses pertains directly to the transfer of electrons between atoms, ions, or molecules. This article presents theoretical treatments of electron transfer with specific attention toward applying these principles to experiment.
Extremely fruitful in many fields of chemistry, the theory Marcus developed in the fifties and sixties describes thermal electron transfer reactions.
