Question
Which of the following is not a state function?
Correct Answer
Option C is the correct answer.
Detailed Explanation
A state function depends only on the current state of the system, not on the path taken to reach it. Entropy, enthalpy, and free energy are state functions. Work (and heat) are path functions, as their value depends on how a change occurs.
Hint
Which of these quantities depends on the pathway, not just the initial and final states?
