The adsorption of ethylene oxide on silver(I) oxide

Abstract

The adsorption of ethylene oxide on stabilized silver(I) oxide in the temperature range 210-373% comprises two processes: (i) A non-activated process with a heat of adsorption from 10.7 to 6.9 kcal mole-l depending on the coverage, which persists over the entire temperature range;     (ii) an activated process with an activation energy at zero coverage of 22.7 kcal mole^-1, which occurs at temperatures greater than 250°K. Reaction between adsorbate and adsorbent ensues above 323%. The generalized Elovich equation has been found to apply to the activated process at high coverage, and an explanation for this is proposed.
