Match the following — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

Adding water (dilution) initially decreases the molar concentrations of all aqueous species (matches C and D). To counteract dilution, the equilibrium shifts toward the side with more aqueous particles. For 1 and 4, the product side has more particles, shifting right, increasing moles of B (matches B). For 2 and 3, the reactant side has more particles, shifting left, increasing moles of A (matches A). Therefore, correct answer is 1-B,C,D, 2-A,C,D, 3-A,C,D, 4-B,C,D.
