Electrochemical cell principles from "summary" of Physical Chemistry by Robert G. Mortimer
Electrochemical cell principles are based on the fundamental laws of chemistry and thermodynamics. These principles govern the flow of electrons between chemical species in a cell, leading to the generation of electrical energy. The key players in an electrochemical cell are the two half-reactions that take place at the electrodes. At the anode, oxidation occurs as electrons are released by the oxidation of the reactant. This process results in the generation of electrons that flow through the external circuit to the cathode. At the cathode, reduction takes place as electrons are accepted by the reduction of the reactant, completing the circuit and allowing the flow of current. The driving force behind these processes is the potential difference, known as the cell potential, between the two electrodes. This potential is determined by the standard reduction potentials of the half-reactions a...
