Which of the following is not correct?
  1. (A) is negative for a spontaneous reaction
  2. (B) is positive for a spontaneous reaction✓ Correct
  3. (C) is zero for a reversible reaction
  4. (D) is positive for a non-spontaneous reaction

Answer: (B)

Solution

is negative for a spontaneous process, zero at equilibrium (reversible process), and positive for a non-spontaneous process. So the statement " is positive for a spontaneous reaction" is the incorrect one.

Key confirmed: B.
