Rate of reaction
Question
- A. It increases the volume of the gas
- B. It decreases the number of particles
- C. It increases the frequency of collisions
- D. It lowers the activation energy
Answer
It increases the frequency of collisions
Explanation
The correct answer is It increases the frequency of collisions. This answer directly addresses the question: Why does increasing the pressure of a gas generally increase the rate of 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 pressure will always increase the rate of reaction without considering the specific reaction conditions.
Emphasize that increasing pressure increases the concentration of gas molecules, leading to more frequent collisions, which generally increases the reaction rate.
