An approximation to the dependence of activation energies of simple catalytic reactions and the initial heats of adsorption of gases on metals on the nature of adsorbent and adsorbate

The activation energy, E, of simple catalytic reactions over 3d-oxides and the initial heats of adsorption, Q_ads, of gases on metals are related in a complex way to the enthalpy of formation of oxides and to the electronegativity of the gases involved in the processes.
