- D. Increase the rate of reaction
Answer
Shift to the right
Explanation
The correct answer is Shift to the right. This answer directly addresses the question: In the equilibrium reaction 3H2(g) + N2(g) ⇌ 2NH3(g), if the pressure is increased, what will be the effect on the equilibrium position? 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
Counting Gaseous Molecules Incorrectly
Students often miscount the number of gaseous molecules on one side of the equilibrium equation, leading to incorrect predictions about the effect of pressure changes.
Carefully identify and count only the gaseous molecules on each side of the equation, ensuring to exclude any solids or liquids.
