We present Monte Carlo simulations of
the formation of islands in the case of
the
reaction occurring
via the Langmuir-Hinshelwood mechanism on a square lattice
under steady-state conditions. The model employed takes
into account the effect of anisotropic lateral B-B interactions
on the rates of B diffusion and elementary reaction events.
The results obtained with qualitatively realistic ratio
of the rate of elementary reaction steps indicate that
the average island size depends on the details of diffusion
and reaction dynamics in a similar way as in the earlier studied
case of the simplest A+B reaction running via the Eley-Rideal
mechanism.
