Short explanation

In The effect of changing concentration (HT only), this learning objective focuses on how to (HT only) Explain concentration effects using Le Chatelier's Principle. Within Reversible reactions and dynamic equilibrium, students should keep the idea anchored to The effect of changing concentration (HT only) rather than drifting into a different rate, equilibrium, catalyst, reversible reaction, or graph concept. Key terms to use include HT only, concentration, Le Chatelier's Principle. A strong AQA GCSE Chemistry answer names the exact factor or relationship, explains the particle or equilibrium reason where needed, and links the point back to the question wording with correct units or graph language when relevant.

Misunderstanding Le Chatelier's Principle: To fix this, students should remember that Le Chatelier's Principle states that a system at equilibrium will shift to oppose the change. They should analyze the specific reaction and the number of moles on each side to predict the direction of the shift accurately.
