Quick explanation
Use the area beyond activation energy to explain rate changes
- This point belongs to Kinetics, especially Maxwell-Boltzmann distribution.
- You need to be able to use the area beyond activation energy to explain rate changes.
- The key ideas to know are activation energy.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Maxwell-Boltzmann distribution to exam-style questions, flashcards, and revision notes for Kinetics.
Quick student answer
Which of the following statements about the Maxwell-Boltzmann distribution is true?
Direct answer
The distribution shifts to the right with increasing temperature.
Key terms
- Activation Energy: The minimum energy that must be overcome for a reaction to occur.
- Maxwell-Boltzmann Distribution: A statistical distribution of the energies of particles in a gas, illustrating the spread of molecular speeds.
Common trap
Confusing Activation Energy with Enthalpy: Remember that activation energy is the energy barrier that must be overcome for a reaction to proceed, while enthalpy change is the difference in energy between reactants and products.
