Question 1.
What happens to the equilibrium when the pressure is increased?
Show hintHide hint
Think about how gas volume and pressure relate.
Question 2.
Define Le Chatelier’s Principle.
Show hintHide hint
Consider how the principle applies to various stresses.
3Question 3.
What does increasing the pressure in a gaseous reaction do?
- A: Favors the side with more gas molecules
- B: Favors the side with fewer gas molecules
- C: No effect on the reaction
Show hintHide hint
Think about how gas laws relate.
4Question 4.
True or False: Decreasing pressure in a reaction always favors product formation.
- True
- False
Show hintHide hint
Consider mole count between reactants and products.
Question 5.
A factory uses the reaction 2CO(g) + O2(g) ⇌ 2CO2(g) to produce carbon dioxide. Discuss how increasing and decreasing pressure would affect the reaction's equilibrium.
Show hintHide hint
Count moles of gas on both sides to determine the effect.
Question 6.
Explain how a chemical engineer might use knowledge of pressure effects in designing reactors for the Haber process.
Show hintHide hint
Consider the input and output gases in the Haber process.
