Quick student answer
What should you know about (HT only) State Le Chatelier's Principle as the idea that a system at equilibrium responds to oppose an imposed change?
Direct answer
In Chemistry, this page helps you answer questions about (HT only) State Le Chatelier's Principle as the idea that a system at equilibrium responds to oppose an imposed change 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 Le Chatelier's Principle and equilibrium.
Key terms
- Le Chatelier's Principle: The idea that a system at equilibrium responds to oppose an imposed change. 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.
- equilibrium: A state in a reversible reaction where the rates of the forward and reverse reactions are equal. 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 Le Chatelier's Principle: Remember that Le Chatelier's Principle states that a system at equilibrium responds to oppose the change, which may mean shifting towards reactants or products depending on the specific change.
