Ziff-Gulari-Barshad Model in Zacros

Ziff, Gulari and Barshad were the first to demonstrate kinetic phase transitions in a conceptual model for CO oxidation on the surface of a heterogeneous catalyst [R. M. Ziff, E. Gulari, Y. Barshad (1986) Phys. Rev. Lett. 56: 2553]. Using a mechanism that includes the non-dissociative adsorption of CO, the dissociative adsorption of O2, and the fast CO oxidation reaction Ziff et al., found a second order phase transition from an O-poisoned regime to a reactive regime, and a first order transition from the reactive to the CO-poisoned regime. Such a model can be easily set up in Zacros: this tutorial explains how to create the necessary input files.
