The equilibrium: SOCl₂(g) ⇌ SO₂(g) + Cl₂(g) is attained at 25°C in a closed container and helium gas — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

Adding an inert gas like helium at constant volume does not change the partial pressures or molar concentrations of the reacting gases. Hence, the equilibrium is not disturbed. Therefore, correct answer is D.
