Le Chatelier's Principle
Also known as: Le Chatelier
When a system at equilibrium is disturbed, it shifts to counteract the disturbance. Allows control of industrial processes to maximize desired products.
💡 Intuition
Push on equilibrium, and it pushes back. Add something, and the system uses it up.
Core Idea
Systems at equilibrium resist change by shifting to partially counteract whatever was added or removed.
🔬 Example
🎯 Why It Matters
Allows control of industrial processes to maximize desired products.
⚠️ Common Confusion
Catalysts don't shift equilibrium—they just speed up reaching it.
How to Use Le Chatelier's Principle
When this concept appears in chemistry, it usually controls how you interpret a representation, a quantity, or a change in a system. Students make faster progress when they can explain what le chatelier's principle tells them before reaching for an equation or memorized phrase.
A strong self-check is to say what le chatelier's principle does, what it does not do, and which nearby idea it is easiest to confuse with. That kind of explanation makes later calculations, lab reasoning, and compare pages much more reliable.
