Catalysed Reaction of Hydrogen with Water and the Nature of Over-voltage

IN the electrolytic formation of hydrogen from water an inertia is present, which has to be overcome by a certain amount of over-voltage. The nature of this inertia is still under discussion. It may either be ascribed to the process of the transition of the hydrogen ions from the water into the state of atoms adsorbed on the electrode, or to the process of formation of hydrogen molecules from the adsorbed atoms.
