Abstract: A Monte Carlo study is made of monomer–linear trimer, monomer–bent trimer and dimer–linear trimer surface reactions on substrates made of percolation clusters having varying degrees of surface disorder and on a statistical fractal, the incipient percolation cluster. The phase diagrams show that the branching of the disordered substrate alters the width of the reactive zone, the production value and the character of the irreversible phase transitions. At the ends of the diagrams a linear decrease in the jamming fractions with increasing substrate branching is seen, together with a discontinuous transition between the jamming states and the neighboring absorbent zones.
