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

• Arrow width (stroke_width) represents magnitude of reaction rate
• Use ValueTracker to animate arrow widths smoothly
• Show molecule count bubbles changing when stress is applied
