How fast — rate laws, reaction order and the Arrhenius activation energy.
Thermodynamics says whether a reaction can happen; kinetics says how fast. These simulations let you measure reaction rates on the bench — time the sulfur cross vanishing in the thiosulfate–acid clock, halve the concentration and watch the rate respond, and heat the flask to see the rate leap — then extract the order of reaction, the rate constant, and the activation energy from an Arrhenius plot. Every rate comes from a stopwatch and a concentration, exactly as in the lab.
Beyond the open showcase, subscribed schools get the growing library of Chemical Kinetics experiments — searchable, tagged by concept and difficulty, and expanding continuously.
