A set of forty nine metals was classified with respect to chemisorption of carbon monoxide and a set of nineteen transition metals was similarly treated with respect to dissociation of the chemisorbed molecule. In both cases the metals were characterized by a set of fifteen variables of basic physical importance. Dimensionality reduction yielded eight linearly weakly dependent variables related to chemisorption of CO whereas the reduced set for dissociation had four parameters only. The physico-chemical significance of the characterizing linearly weakly dependent variables is discussed.

The catalytic activity of transition metals in hydrogenolysis of ethane was approximated by a polynomial of second order with variables of basic physical importance, viz., molar heat capacity, covalent atomic radius of the metal, heat of melting, and first ionization potential of the metal atom. The physico-chemical significance of the correlation of these variables with the catalytic activity of transition metals is discussed.

Fundamental Physical

Forty nine metals characterized by a set of fifteen fundamental physical variables were classified with respect to chemisorption of hydrogen. Dimensionality reduction of this physical model led to the determination of nine linearly almost independent variables. This reduced set discriminated the chemisorbing metals from the inactive ones to a satisfactory extent. The physico-chemical significance of these variables for the chemisorption of hydrogen as one of the elementary steps of Fischer-Tropsch catalytic process is discussed.

Pauling Electronegativity

The class structure of transition metals chemisorbing carbon monoxide was determined by expressing the following fundamental parameters in the form of functions: The molar heat capacity, the 1st and 2nd ionization energy, the heat of fusion, Pauling electronegativity, the electric conductivity, Debye temperature, the atomic volume of metal. Adsorption heats have been predicted for twelve transition metals.
