Question 1.
What is Le Chatelier's principle?
Show hintHide hint
Consider how a disrupted equilibrium responds.
Question 2.
What role does a catalyst play in a chemical reaction?
Show hintHide hint
Think about how catalysts influence reaction speed.
3Question 3.
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
Show hintHide hint
Consider how equilibrium balances concentrations.
4Question 4.
Catalysts change the Kc value of a reaction.
- True
- False
Show hintHide hint
Reflect on how catalysts work in reactions.
Question 5.
Given the reaction N2 + 3H2 ↔ 2NH3, if a pressure increase causes the system to shift right, how can one experimentally determine the Kc?
Show hintHide hint
Think about how equilibrium concentrations relate to Kc.
Question 6.
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?
Show hintHide hint
Remember Le Chatelier's principle applies in this scenario.
