Question
Draw a Maxwell-Boltzmann distribution curve and label the activation energy. Explain how the curve changes with an increase in temperature.
Answer
The curve shifts to the right and becomes flatter with an increase in temperature, indicating that more particles have higher energy, thus increasing the number of successful collisions above the activation energy.
Explanation
This answer is strong as it requires the student to demonstrate their ability to draw and interpret the Maxwell-Boltzmann distribution, linking temperature changes to reaction rates, which is a key concept in kinetics.
Common mistake
Misunderstanding Activation Energy
Students often confuse activation energy with the overall energy change of a reaction, thinking it is the energy released or absorbed during the reaction.
Activation energy is the minimum energy required for a reaction to occur, not the energy change. To clarify, remember that activation energy is a barrier that must be overcome for reactants to transform into products.
