just need to understand something between oxygen and ozone
Experiments show that it takes more energy to break the bond between oxygen atoms in the molecule than in the molecule.
How can you explain this?
Diatomic oxygen has a double bond between two oxygen atoms. Ozone, which is molecule of three oxygen atoms, has a single bond and a double bond among the atoms and It takes more energy to break a single bond than a double bond , It would take a photon of less than 242 nm to break the single bond in ozone because it takes more energy to break a single bond than a double bond. Photons in the range of 200-242 nm will break oxygen-o7ygen single bonds. Photons in the range of 242-300 nm will oxygen-oxygen double bonds, takes more energy to break the bond between O3 molecules than in O2 .
