Reaction is characterized by a strong adsorption of CO on the catalyst and a comparatively weak adsorption of H2 (or D). Expressions for the velocity of reaction, is derived from experimental measurements, are: VCH4=k(pH2)0.9/(pCO)0.2, VCD4=k’(pD2)0.7/(pCO)0.2. The reaction is not inhibited by the products of the reaction. The energies of activation are: ECH4=27,000 cal., ECD4=25,000 cal. LYNCH, M. A. See abs. 355a. |
