NEET Chemistry Le Chatelier's Principle MCQ Question
Which of the following statements regarding Le Chatelier's Principle is correct?
Increasing the concentration of reactants shifts the equilibrium towards the products.
Decreasing the pressure in a gaseous reaction always increases the yield of products.
Removing a product will shift the equilibrium to the left to replenish the removed substance.
Adding an inert gas at constant volume changes the equilibrium position.
Correct Answer
Detailed Explanation
According to Le Chatelier's Principle, increasing the concentration of reactants shifts the equilibrium towards the products, as seen in the example of adding potassium thiocyanate to increase the color intensity. Decreasing pressure does not always favor product yield, and removing a product shifts equilibrium to the right, not left. Adding an inert gas at constant volume does not affect equilibrium position.
