Question

At equilibrium, the total entropy change is zero.

• A. The statement is True
• B. The statement is False
  
• C. At equilibrium, the entropy change is not zero.
  
• D. Option B and C

Answer 1

The correct option is A The statement is True

For a reversible process, entropy behaves as a conserved quantity and no change occurs in total entropy. More specifically, total entropy is conserved in a reversible process and not conserved in an irreversible process.

At equilibrium as the system will be reversible so the total change in entropy will be zero.
