Question
- A. The side with more molecules of gas.
- B. The side with fewer molecules of gas.
- C. It will not shift at all.
- D. The side with equal molecules of gas.
Answer
The side with fewer molecules of gas.
Explanation
The correct answer is The side with fewer molecules of gas.. This answer directly addresses the question: If the pressure of a gaseous equilibrium is increased, which side will the equilibrium shift towards? It matches the approved Chemistry 8462 learning objective and the linked subtopic. The other options are incorrect because they either change the rate, catalyst, reversible reaction, equilibrium, or graph context, or they do not answer the exact point being tested.
Common mistake
Misunderstanding Pressure Effects
Students often think that increasing pressure always increases the rate of reaction instead of understanding that it affects the position of equilibrium.
Focus on how increasing pressure shifts equilibrium towards the side with fewer gas molecules, as explained by Le Chatelier's Principle.
