Model of the A B — 0 reaction

Such people should be forced to wear buttons with a figure zero to highlight them. 

In the examples considered above traps B were assumed to serve as sinks of the infinite capacity. Its simple modification for the case of saturable traps (the policeman who caught some toper is no longer on his post but is bringing him to the police station) leads us immediately to the new class of reactions known as A -h B C (C is a neutral reaction product - the policeman bound to a toper is out of his duty) or A-f B 0 (reaction product leaves the system). This latter reaction is typical for the so-called Frenkel defects in solids when complementary defects A and B (interstitial atoms and vacancies) annihilate each other, thus giving no products and restoring the perfect crystalline lattice. 

Another example gives us the reactions on the catalyst surface, considered in the last Chapters of this book, where products depart to the gas phase. In
