Interactions between adsorbed reaction intermediates at high surface coverages may have significant effects on the reaction rates and selectivities predicted by microkinetic modeling for heterogeneous catalysts. This hypothesis is investigated using a simple model for adsorbate-adsorbate interactions to calculate the predicted shifts in the CO methanation rates of transition metals.
