- We explore simple lattice-gas reaction models for CO-oxidation on 1D and 2D periodic arrays of surface adsorption sites. The models are motivated by studies of CO-oxidation on RuO<sub>2</sub>(110) at high-pressures. Although adspecies interactions are neglected, the effective absence of adspecies diffusion results in kinetically-induced spatial correlations. A transition occurs from a random mainly CO-populated steady-state at high CO-partial pressure p<sub>CO</sub>, to a strongly-correlated near-O-covered steady-state for low p<sub>CO</sub> as noted. In addition, we identify a second transition to a random near-O-covered steady-state at very low p<sub>CO</sub>.
