(a)
To determine: If the entropy of the system is increasing or decreasing in the process of photodissociation of O 2 ( g ) .
Solution: The entropy of the system is increasing in the given process.
Explanation:
The process of photodissociation of oxygen gas involves the breaking of bonds which results in the increase in volume and vibrations in the system. Due to this, the randomness of the system increases which results in the increase in entropy of the system.
Conclusion:
The entropy of the system is increasing in the given process.

(b)
To determine: If the entropy of system increasing or decreasing in the process of formation of ozone from oxygen molecules and oxygen atoms.
(c)
To determine: If the entropy of the system is increasing or decreasing in the process of diffusion of CFCs into the stratosphere.
(d)
To determine: If the entropy of the system is increasing or decreasing in the process of desalination of water by reverse osmosis.
