Reaction Rate Simulator — Test the Four Factors

Set temperature, concentration, surface area, and (optionally) a catalyst. Watch the reaction rate change in real time.

Particle box

Reactant (A) Reactant (B) Product (AB) Catalyst (cycles)

Each tick: random collisions happen. A collision succeeds when the combined kinetic energy exceeds the activation energy (Ea). Catalyst lowers Ea by ~40%.

Controls

Temperature 300 K

Concentration 30

Surface area ×1

Catalyst — lowers activation energy

Try it: which factor matters most?

Set baseline (T=300, C=30, S=×1, no catalyst). Note the rate. Then change only one factor at a time. Which change produces the biggest rate increase? Why does that match collision theory?

Predicted ordering (largest effect first): catalyst > temperature > concentration ≈ surface area, for this simulator.
