In the stratosphere, chlorine atoms react with ozone molecules to form chlorine monoxide and oxygen. :Cl· + → ClO· + This reaction causes the depletion of the ozone layer. This reaction can go on and the ClO· radicals can go on to react as such: :ClO· + O· → Cl· + regenerating the chlorine radical. In this way, the overall reaction for the decomposition of ozone is catalyzed by chlorine, as ultimately chlorine remains unchanged. The overall reaction is: :O· + → + 2 This has been a significant impact of the use of CFCs on the upper stratosphere. The nonreactive nature of CFC's allows them to pass into the stratosphere, where they undergo photo-dissociation to form Cl radicals. These then readily form chlorine monoxide, and this cycle can continue until two radicals react to form dichlorine dioxide, terminating the radical reaction. Because the concentration of CFCs in atmosphere is very low, the probability of a terminating reaction is exceedingly low, meaning each radical can decompose many thousands of molecules of ozone. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chlorine monoxide」の詳細全文を読む スポンサード リンク
