(a)
Interpretation:
The entropy change (
Concept introduction:
Entropy is defined as the ratio of thermal energy to the temperature which is unavailable for work done. It is also defined as the measure of disorder of molecule of a system. It is an extensive property and state function.
Entropy is related with the number of microstates for a system and microstate is defined as the number of ways for the system to be arranged.
The standard entropy change at room temperature is equal to the difference between the standard entropy of reactant and standard entropy of product.

Answer to Problem 22QAP
Explanation of Solution
Given process is:
