1. What determines the relative amounts of reactants and products at equilibrium?
- A. The colour of the reactants
- B. The conditions of the reaction
- C. The size of the container only
- D. The names of the substances
2. If temperature is raised in a reversible reaction, what happens to the yield of the endothermic direction?
- A. It decreases
- B. It increases
- C. It stays the same
- D. It becomes zero
3. In a gaseous reversible reaction, increasing pressure favours which side of the equation?
- A. The side with more gas molecules
- B. The side with fewer gas molecules
- C. Neither side is affected
- D. The liquid products only
4. A reversible reaction has 2 moles of gas reactants forming 4 moles of gas product. What happens to the yield of product if pressure is increased?
- A. Yield increases
- B. Yield decreases
- C. Yield is unaffected
- D. The reaction stops
5. A manufacturer could increase yield by using a much higher pressure, but chooses not to. Which is the best explanation?
- A. Higher pressure always destroys the product
- B. The cost of stronger equipment for higher pressure may outweigh the benefit of extra yield
- C. Pressure never affects gaseous equilibria
- D. Higher pressure makes the reaction irreversible
