AQA Chemistry GCSE and AS level, Explaining equilibrium 6-mark question development

This student‑led worksheet is designed to support pupils in developing high‑quality responses to AQA GCSE Chemistry or AQA AS Chemistry equilibrium 6‑mark questions, with a clear focus on extended explanation, application and evaluation.
Students first assess whether they are ready to answer an exam‑style question on industrial equilibrium. Those who need further support are guided through a structured sequence of tasks that carefully build from recall and description to analysis, prediction and justification.
The worksheet explicitly links command words to required thinking skills, helping students understand what examiners are looking for in higher‑mark questions.

Key features include:
Exam‑style 6‑mark equilibrium question (yield, rate and cost)
Clear links to Le Chatelier’s Principle
Progressive tasks aligned to SOLO taxonomy levels
Explicit focus on pressure, temperature and catalysts
Command word support to improve exam technique
Model answers provided for self‑assessment or teacher feedback
Extension task using graph interpretation and industrial context

Ideal for:
GCSE Chemistry (AQA Trilogy or Separate, higher tier – Paper 1)
Developing extended response and evaluation skills
KS4 revision lessons
KS5 lesson or homework
Stretch and challenge
Independent or paired learning
Intervention or exam practice lessons

Topics covered:
Chemical equilibrium
Le Chatelier’s Principle
Effect of temperature, pressure and catalysts
