Ig. Pitt et al., THE APPLICATION OF TRANSITION-STATE THEORY TO GAS-SURFACE REACTIONS .3. LATTICE-GAS SYSTEMS WITH ADSORBATE INTERACTIONS, Surface science, 326(3), 1995, pp. 361-369
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.
