Question
Why does increasing temperature lead to a higher reaction rate?
Answer
Increasingtemperature raises the energy of the particles, which increases their speed. As a result, the frequency of collisions between particles increases, and a greater proportion of these collisions have sufficient energy to overcome the activation energy barrier.
Explanation
This answer effectively explains the mechanism behind the effect of temperature on reaction rate, linkingparticle energy and collision frequency. The question assesses the student's ability to apply their knowledge of collision theory to explain a chemical phenomenon.
Common mistake
Misunderstanding Temperature Effects
Students often think that increasing temperature always leads to a faster reaction rate without considering other factors.
Emphasize that while increasing temperature generally increases reaction rate due to more energetic collisions, it is important to consider the specific reaction conditions and other influencing factors.
