They do not appear in the reaction’s net equation and are not consumed during the reaction. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. Enzymes are biological catalysts.

This may be described as homogeneous catalysis and, compared to heterogeneous catalysis, is a relatively new development in the area of hydrogenation reactions. Rhodium and ruthenium salts appear to be generally useful catalyst.

(a) Hydrogen is adsorbed on the surface, breaking the H–H bonds and forming Ni–H bonds. (b) Ethene is adsorbed on the surface, breaking the π bond and forming Ni–C bonds. (c) H atoms diffuse across the surface and form new C–H bonds when they reach ethene molecules. (d) The saturated carbon atoms in C 2 H 6 molecules can no longer bond to the surface so the ethane molecules es…
