The idea

What is Le Chatelier's principle?

Le Chatelier's principle predicts how a chemical system at equilibrium responds when it is disturbed: the position of equilibrium shifts in the direction that partly counteracts the change. Add more reactant and the forward reaction is favoured; raise the temperature and the endothermic direction is favoured; raise the pressure and the side with fewer moles of gas is favoured. A catalyst changes none of this, only how quickly equilibrium is reached.

Where it appears: Class 11 CBSE, GCSE and A-level, IB Chemistry, AP Chemistry, JEE and NEET.

Where learners get stuck

Why Le Chatelier's principle is hard

Learners say the system undoes the change completely rather than partly, and think pressure affects every reaction when it matters only if the moles of gas differ between sides.

The picture a good explanation starts with: A balanced seesaw labelled reactants and products, with a weight added to one side and an arrow showing the equilibrium tilting to the other side to compensate.

A lesson, step by step

How a lesson on Le Chatelier's principle goes

  1. 01

    Ask

    Type or say "Why does increasing pressure favour fewer gas molecules?" in your own words, in any of 26 languages.

  2. 02

    Plan

    The tutor plans a storyboard, one picture per idea, starting with a balanced seesaw labelled reactants and products, with a weight added to one side and an arrow showing the equilibrium tilting to the other side to compensate.

  3. 03

    Explain

    It explains Le Chatelier's principle out loud while the picture builds step by step, pitched to your level (Class 11 CBSE and up).

  4. 04

    Interrupt

    Say "wait, why?" or type a doubt: it stops, answers over the picture, and carries on. Ask for a different explanation any time.

  5. 05

    Check

    A checkpoint question makes sure the idea landed, and Test Lab keeps the practice going.

  6. 06

    Your notes

    Upload a PDF or a photo of your class notes or a past paper and the lesson follows your textbook's terms.

Ask it anything

Questions learners ask about Le Chatelier's principle

  • Why does increasing pressure favour fewer gas molecules?
  • Does a catalyst shift the position of equilibrium?
  • How does temperature change the equilibrium constant?

Any of these, or your own, typed or spoken. The tutor answers on the picture and adapts to how well you are following.

Questions

Asked, Answered

Can LetMeTeach explain Le Chatelier's principle?

Yes. Ask in your own words and the tutor plans a lesson on Le Chatelier's principle: it starts with a balanced seesaw labelled reactants and products, with a weight added to one side and an arrow showing the equilibrium tilting to the other side to compensate. Then it explains each step out loud as the picture builds, stops when you say "wait, why?", and ends with a checkpoint question.

Where does Le Chatelier's principle come up?

Class 11 CBSE, GCSE and A-level, IB Chemistry, AP Chemistry, JEE and NEET. The lesson is pitched to your level and the exam or curriculum you follow, and you can upload your own notes or past papers so it uses your textbook's terms.

Can I learn Le Chatelier's principle in my own language?

Yes. LetMeTeach teaches in 26 languages and plans the lesson in the language you choose rather than translating an English one, so the terms match what your textbook says. The Free plan includes 7 hours a month with no card.
