Experiments show that it takes more energy to break the bond between oxygen atoms in the {\rm O}_{2} molecule than in the {\rm O}_{3} molecule.
How can you explain this?

Thanks

 

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 .
