Match Column I with Column II — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

For A: Δn = 0, so it is unaffected by pressure or inert gas addition (1 matches A, C). For B: Δn = 1, so a pressure rise shifts it backward, and inert gas at constant pressure shifts it forward (2 matches D). For C: Δn = -2, so a pressure rise shifts it forward, and inert gas at constant pressure shifts it backward (3 matches B). For D: Δn = 1, behaving like B (4 matches D). Therefore, correct answer is 1-A,C, 2-D, 3-B, 4-D.
