Abstract

We have developed and employed the technique of surface temperature modulation to examine the dynamics of the oxidation of Ca on the Pt(110)-(1×2) surface [2]. This technique permits a straightforward analysis of the energetics of elementary surface reactions even in the presence of strong nonlinearities, providing a decided advantage over competing techniques such as modulated molecular-beam reactive scattering. We shall emphasize here the coverage dependence of the kinetic rate parameters (Er and kr(2)Z)) that describe the elementary surface reaction CO(a) + O(a) → CO2 (g). These data will be compared briefly with results obtained previously concerning the coverage dependence of the energy retained in the translational [3] and internal [4,5] modes of the product CO2 molecule.
