摘要: We present isothermal measurements of CO adsorption and desorption rates on Ni(110) that reveal clearly the participation a precursor state in both processes at all coverages. Accounting for its effect allows activation energies preexponential factors to be determined are specific coverage regimes where c(8×2), c(4×2), (2×1) ordered structures known form low temperatures. The include significant contribution attributable relaxation adsorbed layer from one structure another as proceeds, process is also manifested relationship between measured integral heats adsorption. results have general implications systems involving series overlayers.
