THE APPLICATION OF TRANSITION-STATE THEORY TO GAS-SURFACE REACTIONS .3. LATTICE-GAS SYSTEMS WITH ADSORBATE INTERACTIONS

Current perceptions of transition state theory (TST) exclude it from m eaningful description of the sticking coefficient for partially covere d surfaces. This paper extends previous work that enabled TST to descr ibe Langmuir systems to the description of lattice gas systems with ad sorbate interactions. A model calculation is presented illustrating th e TST prediction of the coverage and temperature dependence of the sti cking coefficient. It is concluded that the principal effect of adsorb ate interactions on a lattice gas system is to cause an increase of th e TST sticking coefficient with increasing temperature.
