What is electrode potential?
Electrode potential, also known as redox potential or electrode voltage, is a measure of the tendency of a chemical species to gain or lose electrons when it is involved in a redox (reduction-oxidation) reaction. In simpler terms, it represents the ability of a substance to be oxidized or reduced at an electrode. The electrode potential is typically measured in volts (V) and is defined with respect to a reference electrode. The standard hydrogen electrode (SHE) is often used as the re

What is delta G = -nFE?
This is the Gibbs free energy formula for electrochemical reactions: ΔG = change in Gibbs free energy (J or kJ) n = number of moles of electrons transferred F = Faraday's constant (96,485 C/mol) E = cell potential (volts) Relates electrical work to free energy change in redox reactions. Negative ΔG indicates spontaneous reaction.
