Question 1
What happens when the concentration of a product is increased at equilibrium?
- The reaction shifts left
- The reaction shifts right
- No effect
- Depends on temperature
💡 Hint: Consider how equilibrium balances concentrations.
Question 2
Catalysts change the Kc value of a reaction.

Challenge Problems
Push your limits with challenges.
Question 1
Given the reaction N2 + 3H2 ↔ 2NH3, if a pressure increase causes the system to shift right, how can one experimentally determine the Kc?
💡 Hint: Think about how equilibrium concentrations relate to Kc.
Question 2
A reaction at equilibrium has Kc = 10 at a certain temperature. If product concentration is low, which direction will the reaction move if reactants are added?
💡 Hint: Remember Le Chatelier's principle applies in this scenario.
