For which system at equilibrium, at constant temperature will the doubling of the volume cause a shift to the right?
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Initially, there's 1 mole of gas on the left side and 2 moles on the right side. Doubling the volume (decreasing the pressure) would favor the side with more gas moles to counteract the pressure decrease. The equilibrium would shift to the right to produce more PCl3 and Cl2.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
