6 sample questions

Question 1.
What does the equilibrium constant (K) represent?
Show hintHide hint
Think about what happens when the reaction stops changing.
Question 2.
Define reaction quotient (Q).
Show hintHide hint
Consider how this can indicate the direction of the reaction.
3Question 3.
What happens when Q < K?
- Products are favored
- Reactants are favored
- No change
Show hintHide hint
Think about the direction the reaction will move to reach equilibrium.
4Question 4.
True or False: Both K and Q can be affected by changes in temperature.
- True
- False
Show hintHide hint
This is critical when considering how temperature shifts affect reactions.
Question 5.
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?
Show hintHide hint
Use Le Chatelier’s principle for guidance.
Question 6.
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?
Show hintHide hint
Remember the relationship of K to ∆G.
