Question

A system in thermodynamic equilibrium will have the minimum value for-?

• A. Helmholtz free energy
• B. Gibb's free energy
• C. Entropy
• D. Temperature

Answer 1

Answer: (A), (B)

The correct options are
A Helmholtz free energy
B Gibb's free energy

A system is said to be in thermodynamic equilibrium when the macroscopic particles do not undergoes any change with time.

For a system in thermodynamic equilibrium, at controlled constant temperature and pressure, Gibb's free energy is minimum and at controlled constant temperature and volume Helmholtz's free energy is minimum.
