3334.     ---------------.  [TAYLOR, H. S.]  [Effect of the Heterogeneity of Catalysts on Chemisorption and Chemical Kinetics.]  Jour. chim. phys., vol. 47, 1950, p. 1225; Chem. Abs., vol. 44, 1950, p. 7132.

        Taylor presents his current views on the heterogeneity of surfaces; he points out that the Langmuir, Brunauer-Emmett-Teller, Hüttig, Harkins and Jura adsorption theories all assume a uniform surface and the absence of interaction between adsorbed molecules.  Strictly speaking, this cannot be true, however, and on the basis of recent work in his and other laboratories Taylor reemphasizes the importance of the Freundlich isotherm v=kp¹/ⁿ.
