is added. The mechanism is illustrated in fig. and the chosen ground truth kinetic constants tabulated in table 1 in full complexity. Adsorptions are taken to be non-activated. Desorption of A is promoted at high coverages by itself, loosely inspired by aforementioned self-interactions of CO on Ni surfaces . Product readsorption is highly discouraged but not impossible. The rate constants have been constructed to expect reactions to proceed with roughly the same net rate at stoichiometric conditions and T = 550 K.
