Quick explanation
Define dynamic equilibrium in a closed system
- This point belongs to Chemical equilibria, Le Chatelier's principle and Kc, especially Equilibrium and Le Chatelier's principle.
- You need to be able to define dynamic equilibrium in a closed system.
- The key ideas to know are dynamic equilibrium and closed system.
- 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 Equilibrium and Le Chatelier's principle to exam-style questions, flashcards, and revision notes for Chemical equilibria, Le Chatelier's principle and Kc.
Quick student answer
Which of the following statements best describes dynamic equilibrium in a closed system?
Direct answer
The concentrations of reactants and products remain constant.
Key terms
- Dynamic Equilibrium: A state in a closed system where the rates of the forward and reverse reactions are equal, leading to constant concentrations of reactants and products.
- Le Chatelier's Principle: A principle stating that if a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change.
Common trap
Confusing static and dynamic equilibrium: Remember that in dynamic equilibrium, reactions are still occurring, but the rates are equal, maintaining constant concentrations.
