2025.     KWAN, T.  Adsorption of Carbon Monoxide on Platinum Catalyst.  Jour. Research Inst. Catalysis, vol. 1, 1949, pp. 110-116; Chem. Abs., vol. 44, 1950, p. 4304.

        CO adsorption isotherms were measured at pressures between 0.001 and 1 mm. Hg at 180°, 200°, 280° and 300°.  The differential heat of adsorption is constant for all quantities adsorbed and equals 11 kcal. per mol.  By developing, on a statistical-mechanical basis, an expression for the change in heat of adsorption with fraction of surface covered by adsorbent, assuming that adsorption occurs without dissociation or that CO is dissociated to C and O, better agreement was obtained between observed and calculated values for the latter case.
