How do I simulate a molecular collision?

Open this page and use the live Chemical Equilibrium tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

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 molecular collision from your own measurements.

Equilibrium constant K

Initial [A] (M)

Initial [B] (M)

For A + B ⇌ C + D, the reaction proceeds until the ratio of products to reactants equals K. A large K means products dominate; a small K means the reaction barely proceeds. The extent x is found by solving the equilibrium expression. Educational tool.

[A], [B] at eq.0.333, 0.333 M

[C], [D] at eq.0.667 M

Governing equation

K_{e q} = \frac{[ C ] [ D ]}{[ A ] [ B ]} = \frac{( 0.667 ) ^{2}}{( 0.333 ) ( 0.333 )} = 4

Reading this result: With K = 4, reactants and products coexist; the reaction proceeds to an extent x = 0.67.

About this simulation

The full Chemical Equilibrium tool models a molecular collision 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.
