Question:
A substance is carried out through the given transformations.
A substance is carried out through the given transformations.
Show Hint
State functions (S, H, U) depend only on initial and final states, not path.

- is true only if the steps are carried out reversibly
- is always true because entropy is a state function
- may be true but need more information
- is incorrect

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Entropy ($S$) is a state function, meaning its change depends only on initial and final states, not on the path.
Step 1: Identify paths: A → B → C and A → D → E → C represent different paths between same states.
Step 2: Since entropy is a state function, total change is independent of path taken.
Step 3: Hence, sum of entropy changes along both paths must be equal.
\[ \Delta S_1 + \Delta S_2 = \Delta S_4 + \Delta S_5 + \Delta S_3 \] Conclusion:
The given relation is always true.
