Question 1.
What happens when a reactant is added to a system at equilibrium?
Show hintHide hint
Think about what the system does to counteract the change.
Question 2.
If a product is removed from an equilibrium system, what will happen?
Show hintHide hint
Consider the balance of reactants and products.
3Question 3.
What happens when you add more reactants to an equilibrium?
- It shifts left
- It shifts right
- No change
Show hintHide hint
Refer to Le Chatelier's Principle.
4Question 4.
True or false: Removing a product from an equilibrium will always shift the reaction to the left.
- True
- False
Show hintHide hint
Think about how systems respond to changes.
Question 5.
In the equilibrium reaction H₂(g) + I₂(g) ⇌ 2HI(g), if a large amount of H₂ is added, predict how the concentrations of H₂, I₂, and HI will change.
Show hintHide hint
Use Le Chatelier's Principle to analyze the situation.
Question 6.
Consider the reaction 2SO₂(g) + O₂(g) ⇌ 2SO₃(g). If O₂ is removed from the system, how will the concentration of SO₂ and SO₃ change?
Show hintHide hint
Think about the shift direction based on what's being removed.
