In the equilibrium mixture: H₂(g) + I₂(g) ⇌ 2HI(g), the mole ratio of gases are √2 : √2 : 10, respec — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

For the given reaction, Δn = 2 - (1+1) = 0. Adding an inert gas at constant pressure increases the volume, but since the number of gaseous moles on both sides is equal, the volume terms cancel out in the equilibrium constant expression. Therefore, the equilibrium position and mole ratios remain unaffected. Therefore, correct answer is A.
