  • A More chlorine gas forms
  • B Product concentration disappears
  • C Reverse reaction stops fully
  • D Equilibrium shifts toward PCl₅
Correct Answer: Option D
Explanation:
Reducing volume increases pressure. The system responds by shifting toward the side with fewer gas molecules. The left side has fewer molecules, so more PCl₅ forms.
