Quick explanation
(HT only) Use information about the exothermic or endothermic direction to predict product yield
- This point belongs to Reversible reactions and dynamic equilibrium, especially The effect of temperature changes on equilibrium (HT only).
- You need to be able to (HT only) Use information about the exothermic or endothermic direction to predict product yield.
- The key ideas to know are endothermic direction, HT only, and yield.
- 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 The effect of temperature changes on equilibrium (HT only) to exam-style questions, flashcards, and revision notes for Reversible reactions and dynamic equilibrium.
Quick student answer
What should you know about (HT only) Use information about the exothermic or endothermic direction to predict product yield?
Direct answer
In Chemistry, this page helps you answer questions about (HT only) Use information about the exothermic or endothermic direction to predict product yield within Reversible reactions and dynamic equilibrium. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Exothermic direction and Product yield.
Key terms
- Exothermic direction: The direction of a reversible reaction that releases heat, resulting in a lower temperature of the system. 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.
- Product yield: The proportion of reactants converted into desired products, often expressed as a percentage of the theoretical maximum. 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 Endothermic and Exothermic Reactions: To fix this, remember that increasing temperature favors the endothermic direction, which can increase product yield, while decreasing temperature favors the exothermic direction.
