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
