D1.4 Chemical equilibrium: Pearson BTEC National Applied Science (AAQ) Questions

Practise d1.4 chemical equilibrium with Pearson BTEC National Applied Science (AAQ) questions and mark schemes. Revise D1.4.1 dynamic equilibrium – definition and characteristics, D1.4.2 Le Chatelier’s principle and predicting the effect on equilibrium of changes in concentration, pressure and temperature, and the presence of a catalyst, D1.4.3 equilibrium constant expressions (Kc or Kp) and units.

The topics below follow the course specification. Question availability depends on the papers uploaded; use the question bank filters to see current coverage.

What to revise

• D1.4.1 dynamic equilibrium – definition and characteristics
• D1.4.2 Le Chatelier’s principle and predicting the effect on equilibrium of changes in concentration, pressure and temperature, and the presence of a catalyst

Use questions to check your understanding

Try a question before opening its mark scheme. Show each step in calculations and check the units, significant figures and scientific terms used in your answer. Compare your response with the marking points to see where you can improve.

In the question bank, filter by year and paper, open the original paper, or use split view to compare a question with its mark scheme. The Write tab lets you work on the question and save writing on this device. Add questions to a custom paper for a focused revision session.
