In the context of entropy, what distinguishes between a reversible and irreversible process?

Options

  1. A∆U (change in internal energy)
  2. B∆H (change in enthalpy)
  3. C∆S (change in entropy)
  4. D∆T (change in temperature)

Correct answer

C. ∆S (change in entropy)

Step-by-step solution

The change in entropy (∆S) distinguishes between reversible and irreversible processes. For a reversible process, ∆S is zero, while for an irreversible process, ∆S is not zero.
