Question
Explain how catalysts increase the rate of a chemical reaction in terms of activation energy.
Answer
catalysts increase the rate of a chemical reaction by providingan alternative reaction pathway that has a lower activation energy. This allows more particles to have sufficient energy to collide and react, thus increasingthe frequency of successful collisions.
Explanation
This question tests the understandingof the role of catalysts in chemical reactions, specifically how they affect activation energy. The answer demonstrates knowledge of the concept and its application in explainingreaction rates.
Common mistake
Misunderstanding Catalysts
Students often think that catalysts are consumed in the reaction and therefore do not understand that they can be reused.
Remember that a catalyst is not used up in a reaction; it changes the rate of the reaction by providing an alternative pathway with lower activation energy.
