This exam focus covers Exam Focus: Equilibrium within Equilibrium (HT) for GCSE Chemistry. Revise Equilibrium (HT) in Rates of Reaction for GCSE Chemistry with 20 exam-style questions and 15 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 11 of 13 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.

🎯 Exam Focus: Equilibrium
very-high Le Chatelier questions (3-4 marks HT): State the direction of shift, explain why using the principle, and state the effect on yield.
high Haber process analysis (3-4 marks): Explain the compromise conditions — why 450°C rather than lower temperature, why 200 atm rather than higher.
medium Dynamic equilibrium definition (2 marks): Must include "rates are equal" AND "closed system" AND "both reactions still occurring".
Key phrase to earn marks: "The equilibrium position shifts to the [left/right], increasing/decreasing the yield of [product/reactant]."
