Exam Focus: Equilibrium
Part of Equilibrium (HT) · GCSE GCSE Chemistry revision
This exam focus covers Exam Focus: Equilibrium within Equilibrium (HT) for GCSE Chemistry. Revise Equilibrium (HT) in Rates of Reaction for GCSE Chemistry with 23 exam-style questions and 18 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 11 of 14 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]."
Edexcel 1CH0: Examined in Paper 2 (1CH0/2). Le Chatelier's principle is Higher tier in Edexcel 1CH0 — expect questions on effect of temperature, pressure, and concentration on equilibrium position. In Edexcel-style questions, the command word "Suggest" appears frequently — use your chemistry knowledge to apply to an unfamiliar context.
