Ozone (O³) has a higher molecular weight than Oxygen (O²). Based on weight, O³ should be more prevalent at lower altitudes compared to O², but the opposite is observed in reality. Explain this phenomenon.

Question

Accepted Answer

Ozone (O₃) is found higher in the atmosphere due to its formation process and stability, despite being heavier than oxygen (O₂).

Ozone is formed from oxygen molecules (O₂) when exposed to ultraviolet (UV) light, primarily in the stratosphere.
Ozone's formation occurs at high altitudes where UV radiation is more intense, leading to its concentration in the ozone layer.
O₂ is more stable and abundant at lower altitudes where it is produced by photosynthesis and is essential for life.
The weight of a gas does not solely determine its altitude; factors like temperature, pressure, and chemical reactions play significant roles.
For example, while O₃ is heavier, it is less stable and reacts quickly, which is why it is found in the stratosphere rather than at ground level.

Accepted Answer

Formation of 0³ is only due to splitting of oxygen molecule which happens at height due to ultraviolet radiation
