We present theoretical calculations and Monte-Carlo simulations of a surface reaction model proposed by Fichthorn, Gulari and Ziff (1), on a geometrically disordered lattice. Here we look at this model on a percolation cluster in euclidean dimensions d=2 and d=3. We address the problem of poisoning by a foreign inert species exactly at the percolation concentration.
