Question

For a reversible process at constant pressure and temperature, the free energy change is

• A. greater than zero but less than one
• B. less than zero
• C. equal to zero
• D. greater than one

Hint:

Use ΔG = 0 to identify equilibrium states in reversible processes.

Answer 1

The Correct Option is C

For a reversible process, the change in Gibbs free energy (ΔG) is zero, indicating equilibrium between the system and its surroundings.
