Question 1
What happens when Q < K?
- Products are favored
- Reactants are favored
- No change
💡 Hint: Think about the direction the reaction will move to reach equilibrium.
Question 2
True or False: Both K and Q can be affected by changes in temperature.
- True
- False
💡 Hint: This is critical when considering how temperature shifts affect reactions.

Challenge Problems
Push your limits with challenges.
Question 1
Given a reaction that has an equilibrium constant K = 10 at a certain temperature, what happens to the system if we triple the concentration of reactants?
💡 Hint: Use Le Chatelier’s principle for guidance.
Question 2
Calculate the Gibbs energy change for a reaction at equilibrium where K = 4. Calculating Gibbs at standard conditions leads to ∆G° = -RT ln K. What can we infer about spontaneity?
💡 Hint: Remember the relationship of K to ∆G.
