For a spontaneous process the correct statement is

Options

  1. Aentropy of the system always increases
  2. Bfree energy of the system always increases
  3. Ctotal entropy change is always negative
  4. Dtotal entropy change is always positive.

Correct answer

D. total entropy change is always positive.

Step-by-step solution

S_ total = S_ system + S_ surroundings For a spontaneous process S_ total must be positive. i.e. S_ total >0 .
