Question 1.
What is dynamic equilibrium?
Show hintHide hint
Think about a seesaw.
Question 2.
What does Kc represent?
Show hintHide hint
Relate it to concentrations.
3Question 3.
What happens to the position of equilibrium if you increase the pressure?
- It will shift to the side with fewer moles of gas.
- It will shift to the side with more moles of gas.
- It remains unchanged.
Show hintHide hint
Consider the moles of gas on either side.
4Question 4.
True or False: Equilibrium constants change with concentration.
- True
- False
Show hintHide hint
Think about their definition.
Question 5.
Consider the equilibrium CO(g) + 3H2(g) ⇌ CH4(g) + H2O(g). If you start with equimolar amounts and heat increases the temperature, how does this affect Kc?
Show hintHide hint
Consider the effect of heat on product and reactant concentrations.
Question 6.
Calculate the solubility of BaSO4 in water if Ksp = 1.1 × 10–10, and write its equilibrium expression.
Show hintHide hint
