The mechanism of H<SUB>2</SUB>–D<SUB>2</SUB> equilibration reaction over the copper surface was studied in the 40–90 °C range of temperature and in the pressure range of 4–45 Torr. From the studies of the hydrogen adsorption and the reaction between gaseous deuterium and preadsorbed hydrogen, the reaction was confirmed to proceed <I>via</I> combination between hydrogen and deuterium atoms on the surface. The rate constants for the adsorption and the desorption were optimized by a computer simulation of the reaction-time course and were found to be in satisfactory agreement with the observed results. A marked isotope effect was found in these rates; its influence on the partial pressure dependence of the reaction was discussed.
