Onsager reaction
Web23 de fev. de 2024 · The Onsager reaction jeld as a screened self-interaction 1275 takes the form This exhibits the most important difference between the two formulae (1.1) and (1.4) : when the radius a of the cavity has a fixed value, as Bottcher (1942, p 947) assumes, the Onsager reaction field correction fa in equation (1.3) is linear in nci = (m2 - 1)/4.n for Web2. 2 ONSAGER 's Theorem. A rigorous description of thermal influences on the electrical current and vice versa has been presented by ONSAGER2.19 in 1931 [ 83, 84 ]. His theory discusses the relations of reciprocity of reversible and irreversible processes, where the coupling of the electrical and the thermal subsystems are investigated.
