The complicated reaction kinetics of NO desorption and decomposition w
ere adequately simulated within the framework of a deterministic model
considering interactions in the adsorbed layer. The repulsive interac
tions between N and NO adparticles together with the strong inhibition
of NO dissociation by NO, N and O adsorbates were shown to be respons
ible for the peculiarities of N-2 and NO TPD spectra from the Rh(111)
surface.
