WebOzone formation takes place by placing dry oxygen in ozonizer and passing it through high voltage electric current by silent electric discharge. ... Formation of Ozone. The reaction of UV radiation with O 2 or dioxygen molecules results in the formation of O 3. The UV radiation splits the oxygen molecule into the free oxygen or O atoms. Web29 de jan. de 2024 · Ozone is produced naturally when highly energetic UV radiation breaks down oxygen molecules and cause them to split apart in a process called photolysis. If a free oxygen atom collides with another oxygen moleule, it joins up, forming ozone. O X 2 + U V 2 O O + O X 2 O X 3 So, why most of the ozone resides in stratosphere?
