Match Column I with Column II — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

All reactions are endothermic dissociations, so α increases with T (B). Inert gas at constant volume doesn't change partial pressures (C). Increasing pressure decreases volume, increasing all concentrations initially (D). H₂ is a product in 1 and 3, so adding it shifts equilibrium back (A). For reaction 3, Δn = 0, so α is independent of pressure (E). Therefore, correct answer is 1-A,B,C,D, 2-B,C,D, 3-A,B,C,D,E, 4-B,C,D.
