  1. Question 1

    Q1. For a reversible process, the change in Gibbs free energy (ΔG) is

    • A) zero at constant T and P
    • B) positive at constant T and P
    • C) negative at constant T and P
    • D) independent of T and P

    Answer: zero at constant T and P

    Explanation: ΔG = 0 for a reversible process at constant T and P, indicating equilibrium.
