Le Chatelier's Principle
Description
Demonstrates Le Chatelier's Principle using the Haber process (N₂ + 3H₂ ⇌ 2NH₃). Shows three stresses applied to a system at equilibrium and how the equilibrium position shifts in response to each stress using arrow-size animations.
Phases
| # | Phase Name | Duration | Description |
|---|---|---|---|
| 1 | Title | ~3s | Title appears |
| 2 | Equilibrium intro | ~5s | Equation shown; forward and reverse arrows equal size |
| 3 | Stress 1: Add reactant | ~8s | Add N₂ → forward arrow grows, system shifts right |
| 4 | New equilibrium 1 | ~4s | Arrows balance at new position |
| 5 | Stress 2: Remove product | ~8s | Remove NH₃ → forward arrow grows again |
| 6 | New equilibrium 2 | ~4s | System shifts right again |
| 7 | Stress 3: Increase pressure | ~7s | Fewer moles on right (2 vs 4) → shifts right |
| 8 | Outro | ~3s | Summary of Le Chatelier's rule |
