Match the following — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

Using the relation K_p = K_c(RT)^Δn. For A: Δn = 2 - 2 = 0, so K_p = K_c (1 matches D). For B: Δn = 2 - 4 = -2, so K_p = K_c(RT)⁻² (2 matches C). For C: Δn = 2 - 1 = 1, so K_p = K_c(RT) (3 matches A). For D: Δn = 2 - 0 = 2 (solid is ignored), so K_p = K_c(RT)² (4 matches B). Therefore, correct answer is 1-D, 2-C, 3-A, 4-B.
