How to use: Press a button to stress the system. Watch the color, the bars and the graph. The system shifts to oppose the change, then settles at a new equilibrium.
N₂O₄ (colorless) ⇌ 2 NO₂ (brown) Heat is absorbed going right (endothermic).
Add or remove:
Change temperature:
Change the volume (pressure):
Start by pressing a button. Watch the system shift and settle.
Illustrative data (a simple model; the equilibrium amounts match the Chapter 9.2 data table). This simulation is a simple model for learning, not a real lab measurement.
