The phenomenon of CO*/CO exchange on Pd(111) was investigated by the isotope switch method at temperatures from 100 to 400K. The exchange rate at low temperature regime is different from that in the high temperature regime. The data showed that the exchange rate was related to the migration of the adsorbed molecules and the exchanged reaction activation energy can be expressed by the migration activation energy of the adsorbed molecules.
