(a)

Interpretation:
The missing standard entropy values of the reactants and products has to be calculated for the given set of reactions.
Concept introduction:
Entropy is the measure of randomness in the system. Standard entropy change in a reaction is the difference in entropy of the products and reactants.
Where,
Standard entropy change in a reaction and entropy change in the system are same.
