For a spontaneous process, free energy__________________?
Correct answer: C. Decreases whereas the entropy increases
- A. Is zero
- B. Increases
- C. Decreases whereas the entropy increases
- D. And entropy both decrease
Explanation
At constant temperature and pressure, spontaneity requires Gibbs free energy to decrease, while the entropy of the universe increases. The system's own entropy need not increase, so the entropy statement is understood as total entropy.
