Question
What is activation energy in the context of chemical reactions?
Answer
Activation energy is defined as the minimum energy that reacting particles must possess in order to successfully collide and initiate a chemical reaction.
Explanation
This question tests the student's understanding of a key concept in reaction kinetics, specifically the energy barrier that must be overcome for reactions to occur. It is fundamental for grasping how reactions proceed and the factors that influence their rates.
Common mistake
Confusing Activation Energy
Students often confuse activation energy with the overall energy change of a reaction.
Remember that activation energy is the minimum energy required for particles to react, while overall energy change refers to the difference in energy between reactants and products.
