Abstract: The influence of interaction and lattice coordination number on the reactivity and structure of adsorbed particles on a surface has been analysed for a reaction of a monomer and a dimer that dissociates, both of which are adsorbed on a surface and react. For the case without interaction there is a narrow range for a control parameter in which reaction is effective. Depending on the interaction, this range can grow very large, spanning almost all the range of the control parameter or, on the contrary, the reaction can disappear. Aggregates of adsorbed particles with fractal structure have been observed. Fractal dimension has been determined for different values of a control parameter for square and triangular lattices.
