JEE Main · ChemistryEasy
For a reaction to be spontaneous at constant temperature and pressure, the change in Gibbs free energy must be:
- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: C —
Solution
- Spontaneity at constant temperature and pressure is determined by the Gibbs free energy change .
- If , the process is spontaneous.
- If , the process is non-spontaneous.
- Hence the answer is (C).
