Abstract
THE thermodynamics and kinetics of the chemisorption of hydrogen on metals are of considerable importance for the elucidation of the mechanism of hydrogenation reactions catalysed by these metals. Although extensively studied, the process still remains rather obscure because the evidence is in many respects conflicting. O. Beeck et al.1 and E. K. Rideal and B. M. W. Trapnell2, for example, report that, working with metal films such as nickel, the adsorption velocity is immeasurably rapid. Only a small amount of the hydrogen adsorbed shows a measurable rate of adsorption. Increasing the temperature of adsorption causes a considerable decrease in total adsorption, which is ascribed to the combined effects of desorption and sintering. However, the amount of hydrogen slowly adsorbed remains about the same. They consider the slow process to be a solution of the hydrogen in the nickel structure.
