Question
- A. It decreases the reaction rate
- B. It has no effect on the reaction rate
- C. It usually increases the reaction rate
- D. It only affects solid reactants
Answer
It usually increases the reaction rate
Explanation
The correct answer is It usually increases the reaction rate. This answer directly addresses the question: How does increasing gas pressure typically affect the rate of a chemical reaction? 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 gas pressure has no effect on reaction rate.
Explain that increasing gas pressure reduces the volume available for gas molecules, leading to more frequent collisions and a faster reaction rate.
