(a) Interpretation: The reason for the negative value of Δ S ∘ when number of gaseous molecules increases in a system needs to be determined. Concept introduction: Entropy is defined as degree of randomness in a system. It is due to the random motion of molecules in the reaction system. The entropy of a gaseous system is more than a liquid system as gaseous molecules are in constant motion. If number of gaseous molecules increases, entropy also increases.

Concept introduction:
Entropy is defined as degree of randomness in a system. It is due to the random motion of molecules in the reaction system. The entropy of a gaseous system is more than a liquid system as gaseous molecules are in constant motion. If number of gaseous molecules increases, entropy also increases.
Interpretation Introduction
(b)
Interpretation:
The reason for ΔS∘ value to be independent of T needs to be explained.
Concept introduction:
Entropy is defined as degree of randomness in a system. It is due to the random motion of molecules in the reaction system. The entropy of a gaseous system is more than a liquid system as gaseous molecules are in constant motion. If temperature of a system is increased, the random movement of molecules of gases increases.
