STANDARD Chemistry Le Chatelier's Principle MCQ Question
For the reaction PCl₅(g) ⇌ PCl₃(g) + Cl₂(g), the forward reaction at constant temperature is favoured by
introducing an inert gas at constant volume
introducing Cl₂ at constant volume
increasing pressure
decreasing pressure
Correct Answer
Detailed Explanation
Decreasing pressure favors the forward reaction as it shifts the equilibrium towards the side with more moles of gas, which is the product side in this case.
