| Nitrogen Dioxide/Tetroxide Demonstration |
A visual demonstration of Le Chatelier’s principle involves the dynamic equilibrium between nitrogen dioxide and dinitrogen tetroxide gases. Fill a gas syringe with an equilibrium mixture of brown NO2 and colourless N2O4. The effect of pressure is shown by... more |

| Demonstrations With Equations |
Use demonstrations with equations concurrently. Use YouTube demonstrations which clearly show what’s happening |

| Repackage Into Simple Wording |
Le Chatelier’s principle is quite cumbersome in its wording, so break that down into language that’s easier for students to understand - that’s called repackaging. Repackage of the concept and wording into language which students understand and can relate to. For example, if you heat the system... more |

| Red Flag for New Words |
Use red flags on lecture slides every time a 'new' defined word is used, to reiterate the meaning which is different to the meaning they might have encountered before. Even the word ‘equilibrium’ which has a meaning in the chemistry context and an everyday meaning. There will be literally a red... more |

| Differentiate Q and K |
Start by defining the Q and K, and saying that Q is your tool. K is over here and it doesn’t change, but Q is your tool to assess how close we are to K in terms of the system. |
