WebSo the faraday is basically a conversion factor to switch from number of moles of electrons to number of coulombs and vice versa. So to get the total number of coulombs passed for a balanced chemical reaction (aka: a "mole of rxn") you just multiply the number of moles of electrons (\(n\)) by the faraday constant, \(F\). \[q = n\cdot F\] WebNov 16, 2024 · The electrolyser itself is a series of cells with an electrolysis reaction taking place: [6] 2 H20(l) ↔ H2(g) + O2 (g) ΔHrxn = +286 kJ/mol H2. Each electrolyser cell consists of an anode and a cathode separated by a membrane submerged in water. A power supply passes a current through the cell splitting water into hydrogen and oxygen.
