The cellular-automaton (CA) AB2 surface-reaction model of Chopard and Droz (1988) is modified so that the proper stoichiometry in both the B2 adsorption and the AB reaction is followed. Simulations show that the first-order kinetic phase transition of the Monte Carlo AB2 model is recovered. A mean-field analysis which predicts a first-order phase transition, is also presented.
