About chemical equilibrium notes
GoConqr OriginalChemical equilibrium notes to start with
Start with Chapter 15 reading notes for an introduction to equilibrium and the reactions shown by arrows in opposite directions. Then read Chemistry: Further Equilibrium: Chemical Equilibrium for notes on Kc and reactions where all substances are in the same phase.
Follow a topic through the notes
For acid-base revision, Topic 5A: acid-base equilibria covers Brønsted–Lowry acids and the pH scale. Equilibrium Principles in Aqueous Systems introduces the solubility product, Ks. The notes called The Equilibrium Process Part II include Kc and examples of industrial reactions.
As you read, write a short explanation of each term in your own words, then check it against the notes. Compare explanations across resources when you want another description of a topic. Switch to a quiz on the unit page when you are ready to check your recall, or use a mind map to review connections between ideas.
Choose a note and work through one topic at a time.
Frequently asked questions
Which note is a useful place to start?
Try Chapter 15 reading notes for an introduction to the concept of equilibrium. It describes an equilibrium state and shows reactions with arrows in opposite directions. You can then move to Chemistry: Further Equilibrium: Chemical Equilibrium for notes on Kc and homogeneous reactions.
Are these notes free to use?
Yes. Every resource listed here is free to open and study without an account. They were made by GoConqr users. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes.
Who are these notes suitable for?
Most resources are at school level, so school students can use the notes to practise equilibrium concepts and teachers can look for material to use in lessons. There are also some university-level resources. The collection includes notes on dynamic equilibrium, acid-base equilibria and aqueous systems.
