When the chlorine monoxide meets a free oxygen atom, an important step in the catalytic cycle, the oxygen in the chlorine monoxide becomes highly attracted to the free atom and breaks away to form a new oxygen molecule. The "abandoned" chlorine is free to begin ozone destruction anew. 4, record 1, English, - catalytic%20chain

Par exemple, dans le maillon : 03 + C1 - C10 + 02, le chlore agit comme catalyseur. Dans le maillon suivant : C10 + 0 - C1 + O2, le catalyseur se retrouve intégralement après que la substance initiale, l'ozone, ait été détruite. C'est un cycle car, en présence à nouveau d'ozone, le chlore agira encore comme catalyseur. 3, record 1, French, - cha%C3%AEne%20catalytique
