Question 1.
What is dynamic equilibrium?
Show hintHide hint
Think about reactions happening continuously.
Question 2.
What does Le Chatelier's Principle state?
Show hintHide hint
Consider how a balance reacts to weight changes.
3Question 3.
What does Le Chatelier's Principle predict?
- A. The rates of reactions will always be equal.
- B. A system at equilibrium will shift to counteract changes.
- C. All reactions go to completion.
Show hintHide hint
Think about maintaining balance in a system.
4Question 4.
True or False: A catalyst changes the position of equilibrium.
- True
- False
Show hintHide hint
Consider what catalysts do in reactions.
Question 5.
In the reaction 2NO(g) + 2H₂(g) ⇌ N₂(g) + 2H₂O(g), predict the shifts if we decrease the volume. Explain your reasoning.
Show hintHide hint
Consider changes in moles with pressure-volume relationships.
Question 6.
If 10 moles of A(g) ⇌ 5B(g) + 5C(g) is at equilibrium and we suddenly double the temperature, what would you expect regarding equilibrium position if the reaction is endothermic?
Show hintHide hint
Recall how temperature influences reaction direction based on enthalpy.
