For a process to occur spontaneously

Options

  1. Aonly the entropy of the system must increase
  2. Bonly the entropy of the suroundings must increase
  3. Ceither the entropy of the system or that of the surroundings must increase
  4. Dthe total entropy of the system and the surroundings must increase

Correct answer

D. the total entropy of the system and the surroundings must increase

Step-by-step solution

( S )_ system +( S )_ surrounding >0 (irreversible process)
