2599.     PEASE, R. N.  Catalytic Combination of Ethylene and Hydrogen in the Presence of Metallic Copper.  I.  Measurements of Reaction Velocity and Adsorption Isotherms at 0° and 20°.  Jour. Am. Chem. Soc., vol. 45, 1923, pp. 1196-1210; Chem. Abs., vol. 17, 1923, p. 2220.

        Kinetics of the catalytic combination of H₂ and C₂H₄ have been studied at 0° and 20° in the presence of Cu.  The reaction velocity and adsorption isotherms have been determined.  Within limits, the velocity increases with the H₂ concentration but decreases as the C₂H₄ concentration increases.  The temperature coefficient of the reaction velocity/10° rise between 0° and 20° is 1.62, indicating that diffusion does not play a dominant part.
