Chemical Kinetics Simulator

Interactive chemical kinetics simulator: watch reactant molecules A and B collide inside a reaction vessel and convert to product C only when collision energy clears the Arrhenius activation barrier, with temperature, activation energy, catalyst and starting concentration all tunable in real time.

Watch a bimolecular reaction A + B → C unfold at the molecular level. Reactant particles wander the reaction vessel by Brownian motion, and every close approach is checked as a real collision: only pairs whose relative kinetic energy clears the activation-energy barrier convert into product. Temperature, activation energy, a catalyst toggle and starting concentration all feed the same Arrhenius relationship that governs real reaction rates, so the live concentration graph and rate-constant readout respond exactly the way a real kinetics experiment would.

⚙ Under the hood

Molecular-scale bimolecular reaction A + B → C: reactant spheres wander a vessel by Brownian motion and convert to product only when a collision's kinetic energy clears the Arrhenius activation barrier, with a live [A]/[B]/[C] concentration graph and rate-constant readout.
