A CFC is a molecule which consists of Chlorine, Fluorine and Carbon only. Ozone is destroyed due to the formation of a chlorine free radical. For example, the CFC CCl2F2 photo-dissociates (decomposes due to UV rays) to form the chlorine free radical and this then reacts with ozone breaking it down into oxygen. The main problem with CFCs is that after destroying the ozone molecule, the chlorine free radical regenerates and can destroy more ozone in a massive chain reaction.
What else can I help you with?
How do cfc's breakdown the ozone?
CFCs break down ozone in the atmosphere when they are exposed to ultraviolet radiation. This causes the CFC molecules to release chlorine atoms, which then react with ozone molecules, leading to the destruction of the ozone layer.
Why is the CFCs and the ozone layer a concern?
CFC's and ozone layer combined is a concern. It is the problem because CFC's destroy the ozone to a great content.
Why is the reaction of CFC's with ozone considered catalytic?
The reaction of CFCs with ozone is considered catalytic because the CFC molecule remains unchanged after reacting with ozone, allowing it to continue breaking down more ozone molecules. This creates a cycle where a small amount of CFCs can destroy a large number of ozone molecules before eventually being removed from the atmosphere.
What class of molecules has CFCs replace?
CFC's are ozone depleting substances. HCFC's are an alternative to CFC's.
Which compounds have the highest ozone depletion potential ODP?
The compounds with the highest ozone depletion potential (ODP) are chlorofluorocarbons (CFCs), specifically CFC-11 and CFC-12, along with halons. These substances are long-lived in the atmosphere and are able to destroy ozone molecules efficiently.
Is ozone promoted by CFC's?
No, its not. ozone is destroyed by CFC's.
What do you know about ozone layer why did it destroying and flaw can we prevent it?
Ozone layer is a pool of ozone molecule. It is being destroyed by CFC's.
How do cfc's breakdown the ozone?
CFCs break down ozone in the atmosphere when they are exposed to ultraviolet radiation. This causes the CFC molecules to release chlorine atoms, which then react with ozone molecules, leading to the destruction of the ozone layer.
What instances where by the normal ozone is destroyed?
Ozone is destroyed by the CFC gases. CFC converts ozone to oxygen.
How does CFCs effect the ozone?
CFC's react with ozone. They decompose it to deplete it.
What does CFCs do to the ozne layer?
CFC's go in the ozone layer. They deplete the ozone.
How can we affect CFCs?
CFC's are compounds which cause ozone depletion. They decompose ozone.
Why is the CFCs and the ozone layer a concern?
CFC's and ozone layer combined is a concern. It is the problem because CFC's destroy the ozone to a great content.
What does cfc's do to the ozone molecules?
CFCs convert ozone to oxygen. They are responsible for ozone layer depletion.
Why is the reaction of CFC's with ozone considered catalytic?
The reaction of CFCs with ozone is considered catalytic because the CFC molecule remains unchanged after reacting with ozone, allowing it to continue breaking down more ozone molecules. This creates a cycle where a small amount of CFCs can destroy a large number of ozone molecules before eventually being removed from the atmosphere.
What happens when a CFC molecule comes near a ozone molecule?
When CFC molecule comes near ozone, it reacts with it. This leads to depletion of ozone layer.
What is the protective layer of the atmosphere destroyed by CFC's?
The protective layer of the atmosphere that is destroyed by CFCs is the ozone layer. CFCs (chlorofluorocarbons) break down ozone molecules, leading to ozone depletion. This thinning of the ozone layer allows more harmful ultraviolet (UV) radiation from the sun to reach the Earth's surface, posing risks to human health and the environment.
