Answer 1

Answer:

Ozone is found by (a)photochemical dissociation of molecular oxygen into individual oxygen atoms

hope it will be helpful for you!!!!

Plz plz mark as brainliest!!!!

Answer 2

Ozone is formed by the photochemical dissociation of molecular oxygen into individual atoms.

• A photochemical reaction is a chemical reaction where there is the absorption of light by photons.
• Thermochemical reactions are the reactions that involve the absorption or evolution of heat.
• The reactions which are caused by heat and in absence of light are called thermal reactions.
• Ionic reactions are the chemical reactions between ions that are dissociated from any media.
• So ozone is formed by the photochemical dissociation of molecular oxygen atoms.
