Description

Kinetics of adsorption of hydrogen on metal surface has been discussed from the measurements of electrical resistivity change of iron evaporated films on admission of hydrogen gas of various pressures. Similar experiments were carried out for titanium evaporated flims and used for explanation of the adsorption kinetics of hydrogen on iron films.<BR>Kinetic parameters of adsorption are derived from the time response of the resistivity change on the bases of adsorption models. They are compared with the parameters derived from thermodynamical estimation.
