Question

Assertion (A): Gibbs free energy determines spontaneity at constant T and P.
Reason (R): A process is spontaneous when Gibbs free energy is minimum.

• A. Both A and R are true, and R is the correct explanation of A
• B. Both are true, but R is not the correct explanation of A
• C. A is true, R is false
• D. A is false, R is true

Hint:

Remember the criteria:
- Constant $T$ and $P \Rightarrow$ Gibbs Free Energy ($G$) is minimized.
- Constant $T$ and $V \Rightarrow$ Helmholtz Free Energy ($A$) is minimized.
- Isolated System $\Rightarrow$ Entropy ($S$) is maximized.

Answer 1
