Crystallization for a reaction network

Simulate a reaction network live in your browser. This runs the real Crystallization solver — adjust the inputs, watch it respond instantly, and export the result. No install, no account.

Chemical Equilibrium (Le Chatelier)Live
A (reactant)0.67 M
B (product)1.33 M

Controls

A reversible reaction A ⇌ B settles where forward and reverse rates balance. Add reactant or raise temperature and watch the equilibrium shift to relieve the stress.

Governing equation

Reading this result: Effective K is near 1, so A and B coexist in comparable amounts and a small stress can tip the balance either way.

Presets

A phase diagram maps which state — solid, liquid, or gas — a substance takes at each temperature and pressure. The lines are phase boundaries; cross one and the material transforms. All three meet at the triple point, and the liquid-gas line ends at the critical point beyond which liquid and gas become indistinguishable.

Temperature25 °C
Pressure100 kPa

Governing equation

Reading this result: Liquid: warm enough to melt yet below the boiling line at this pressure, so the stable state is liquid water.

About this simulation

The full Crystallization tool models a reaction network with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions

How do I simulate a reaction network?
Open this page and use the live Crystallization tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
Is it free?
Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
Can I use my own numbers?
Absolutely — every input is adjustable, and with data import you can drive a reaction network from your own measurements.
