(a)
Interpretation:
The decreasing standard molar entropy
Concept introduction:
Entropy is a thermodynamic quantity, which is the measure of randomness in a system. The term entropy is useful in explaining the spontaneity of a process. For all spontaneous process in an isolated system there will be an increase in entropy. Entropy is represented by the letter ‘S’. It is a state function. The change in entropy gives information about the magnitude and direction of a process. The entropy of one mole of substance at a given standard state is called standard molar entropy (

In thermodynamics entropy is the term that measures the randomness of the system. The system can have different energy levels and the constituent particles such as atoms and molecules can be arranged in different possible ways. The different possible arrangements of particles are called as the thermodynamic probability. The different possible arrangements are also called as microstates.
