摘要：
After the chemisorption of a polyatomic molecule on an active site of a catalyst, the adsorption energy is localized in the new, molecule-active site bond. Assuming the free flow of adsorption energy into the internal vibrations of the adsorbed molecules only, the Rice-Ramsperger-Kassel (RRK) statistical theory of a spontaneous decomposition can describe the surface reaction of these molecules. The mean vibrational energy of adsorbed molecules is determined by the temperature of reactants in the gas phase, and by the heat of adsorption.
