Question

Ozone Is Formed In The Upper Atmosphere By A Photochemical Reaction With______

Answer 1

Answer:

Ozone is produced naturally in the stratosphere when highly energetic solar radiation strikes molecules of oxygen, O2, and cause the two oxygen atoms to split apart in a process called photolysis. If a freed atom collides with another O2, it joins up, forming ozone O3.

Answer 2

Ozone is formed in the upper atmosphere by a photochemical reaction involving oxygen.

• The ozone blanket present in the upper layer of the atmosphere (stratosphere) protects the Erath from harmful ultraviolet radiation coming from the Sun.
• Ozone is formed by a free-radical photochemical reaction.
• The oxygen molecule present in the atmosphere is converted into oxygen radicles by UV radiation.
• The free radical reacts with another oxygen molecule to form ozone.
• The reactions are as follows:

        O₂ + UV (hν)   →   O° + O°

        O°  + O₂    →  O₃ (Ozone)
