elektronoverførsel

Elektronoverførsel, often abbreviated as ET, is a fundamental chemical process involving the movement of one or more electrons from one molecule or atom to another. This transfer can occur through various mechanisms, including direct contact, tunneling, or through mediating molecules. Electron transfer reactions are crucial in a wide range of natural and artificial systems, playing vital roles in biological processes like photosynthesis and cellular respiration, as well as in industrial applications such as electrochemistry and catalysis.

The driving force behind electron transfer is often the difference in redox potentials between the electron donor and acceptor species. A species with a lower reduction potential readily donates an electron to a species with a higher reduction potential. This process can be spontaneous if the overall reaction is thermodynamically favorable. Understanding the kinetics and thermodynamics of electron transfer is essential for controlling and optimizing many chemical reactions. Factors such as distance between reactants, solvent environment, and the presence of specific ligands can significantly influence the rate and pathway of electron transfer.
