網頁Radical chain-reaction. Now, a radical chain-reaction takes place, during which OH-radicals are formed. The reaction mechanism is as follows: 3: O 3 + O 2 • - -> O 3 • - + O 2. 4: O 3 • - + H + -> HO 3 • (PH < ≈ 8) The OH-radicals that have formed react with ozone according to the following reaction mechanism: 網頁2015年9月1日 · 2. Firstly, ozone is an unstable compound and decomposes at about 573 K to form oxygen. When UV radiation reaches ozone layer, ozone molecules present at the layer absorb its energy and decompose to form oxygen which is more stable than ozone. One ozone molecule decomposes to form one oxygen atom and a normal oxygen molecule. coke bottle cap size https://daniutou.com
