Quick explanation
Explain that the curved line on a reaction profile shows how energy changes as the reaction proceeds
- This point belongs to Exothermic and endothermic reactions, especially Reaction profiles.
- You need to be able to explain that the curved line on a reaction profile shows how energy changes as the reaction proceeds.
- The key ideas to know are curved line and reaction profile.
- 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 Reaction profiles to exam-style questions, flashcards, and revision notes for Exothermic and endothermic reactions.
Quick student answer
How do you explain the curved line on a reaction profile shows how energy changes as the reaction proceeds?
Direct answer
In Chemistry, this page helps you answer questions about the curved line on a reaction profile shows how energy changes as the reaction proceeds within Exothermic and endothermic reactions. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Reaction profile and Curved line.
Key terms
- Reaction profile: A graph showing the energy of reacting particles over time, with a curved line indicating how energy rises to a peak (activation energy) and then falls as products form.
- Curved line: The continuous part of a reaction profile that represents the gradual change in energy of the system as the reaction proceeds from reactants to products.
Common trap
Misinterpreting the reaction profile curve: Explain that the curved line shows the variation in potential energy of the system as reactants convert to products, not the reaction rate
