Question 1
What does the term 'equilibrium' mean in a chemical context?
- Reactants stop reacting
- Rates of forward and reverse reactions are equal
- Products are favored
💡 Hint: Think about balance in a scale.
Question 2
True or False: Le Chatelier's principle shows that equilibrium will always shift to favor products.
- True
- False
💡 Hint: Consider what the system does under pressure or temperature change.

Challenge Problems
Push your limits with challenges.
Question 1
For the equilibrium reaction 3H₂(g) + N₂(g) ⇌ 2NH₃(g), if the equilibrium shifts left when concentration of NH₃ is increased, explain conceptually why that occurs using Le Chatelier’s principle.
💡 Hint: Think about balancing the equation to counteract the added product.
Question 2
Describe how temperature changes would affect the equilibrium of an endothermic reaction like A ⇌ B + heat. If the temperature is raised, what happens?
💡 Hint: Refer to how endothermic reactions absorb heat to shift equilibrium.
