Under Chemical Equilibra, the JAMB Chemistry syllabus expects you to study:

• 13. Chemical Equilibra Reversible reactions and factors governing the equilibrium position.
• Dynamic equilibrium.
• Le Chatelier’s principle and its industrial (i applications, equilibrium constant.
• Simple examples to (i include action of steam on iron and N2O 4 2NO2 (i No calculation will be required

Study notes & guidance

Study Chemical Equilibra using a recommended Chemistry textbook that follows the JAMB syllabus. Work through the contents listed above one by one, make brief notes in your own words, and then practise as many questions on this topic as you can — in Chemistry, understanding and steady practice matter far more than memorising. Use the objectives below as a checklist: if you can do each one confidently, you have mastered this topic.

Objectives — candidates should be able to

After studying Chemical Equilibra, you should be able to:

1. (i) identify the factors that affect the position of equilibrium of a chemical reaction;
2. Predict the effects of each factor on the position of equilibrium; ii)specify the industrial processes where Le Chatelier’s principle is required; and
3. Determine the effects of these factors on equilibrium constant.

These objectives are from the official JAMB syllabus. Use them as a checklist — if you can do each one confidently, you have mastered this topic.
