Question 1

What is Le Châtelier's Principle?

It describes chemical kinetics.
It states how equilibrium systems adjust to stress.
It relates to temperature changes only.

💡 Hint: It's about balancing forces within the system.

Question 2

True or False: Lowering temperature in an exothermic reaction will shift the equilibrium toward products.

True
False

💡 Hint: Consider how heat plays a role in the reaction.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a reaction at equilibrium: P + Q ⇌ R + S, describe the shifts that would occur if the concentration of R is increased. Explain why this shift occurs.

💡 Hint: Consider how the system aims to reduce the excess of R.

Challenge 2 Hard

A closed container holds a gas mixture at equilibrium, but suddenly it expands, reducing pressure. Discuss the expected shift in equilibrium and the reasoning.

💡 Hint: Remember how volume and pressure are interrelated.
