What is the total entropy change for the system and surroundings of a spontaneous process at equilibrium?

Options

  1. AThe total entropy change is maximum.
  2. BThe total entropy change is zero.
  3. CThe total entropy change is negative.
  4. DThe total entropy change is unpredictable.

Correct answer

B. The total entropy change is zero.

Step-by-step solution

At equilibrium, the total entropy change for the system and surroundings is zero, indicating that the system has reached a maximum state of disorder.
