Quick explanation
Explain that catalysts provide a different reaction pathway
- This point belongs to Rate of reaction, especially Catalysts.
- You need to be able to explain that catalysts provide a different reaction pathway.
- The key ideas to know are catalyst.
- 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 Catalysts to exam-style questions, flashcards, and revision notes for Rate of reaction.
Quick student answer
How do you explain catalysts provide a different reaction pathway?
Direct answer
In Chemistry, this page helps you answer questions about catalysts provide a different reaction pathway within Rate of reaction. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are catalyst and reaction pathway.
Key terms
- catalyst: A substance that changes the rate of a chemical reaction but is not used up. In AQA GCSE Chemistry 8462, use this term specifically when explaining rate of reaction, collision theory, reversible reactions, equilibrium, catalysts, graph gradients, or Le Chatelier's principle.
- reaction pathway: The route taken by reactants to form products, which can be altered by the presence of a catalyst. In AQA GCSE Chemistry 8462, use this term specifically when explaining rate of reaction, collision theory, reversible reactions, equilibrium, catalysts, graph gradients, or Le Chatelier's principle.
Common trap
Misunderstanding Catalyst Function: Emphasize that catalysts are not used up and explain their role in lowering activation energy and providing a different reaction pathway.
