How to use: A ⇌ B is a reversible reaction. Blue A particles
turn into green B, and green B turn back into blue A. The particles never stop
reacting — they just reach a balance where the two rates are equal.
Try the buttons: add more A, add more B, or change the temperature.
Watch the graph shift, then settle again at a new balance.
Notice: the reactions never stop — this is dynamic equilibrium.
When you disturb the balance, the system shifts to oppose your change:
add more A → it makes more B. Heat it up → the endothermic direction speeds
up more, shifting the balance. That's Le Chatelier's principle.
