(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.
