Abstract
Stone and Tiley1 have reported that the presence of a chemisorbed film of carbon monoxide reduces the low-temperature physical adsorption of krypton on a copper oxide catalyst. This observation is of particular interest, because the accepted method2 of estimating the area of free metal in a mixed surface involves the assumptions that, at low temperatures, carbon monoxide is initially chemisorbed only on the metal surface, and afterwards physically adsorbed over the whole surface; and that the chemisorbed layer and the bare non-metallic surface have the same adsorption characteristics.
