N2 - The role of adsorbate lateral interactions in surface reaction kinetics is studied for bimolecular reactions A + B → AB. One reactant (A) tends to aggregate into islands, B is mobile and AB is a rapidly desorbing product. A model combining Monte Carlo dynamics for the slow processes (A-aggregation and AB-formation) and an appropriately modified quasichemical approximation for the fast ones (B-redistribution) is used to calculate reaction rates. Reaction desorption spectra and activation energies are calculated for different initial conditions and adsorbate lateral interactions.
