Particle Model of Chemical Reactions (detailed) — free printable diagram

About this illustration

A comprehensive, detailed labeled diagram illustrating the particle model of chemical reactions. The image is structured in three main sections: (1) a three-step reaction sequence showing Reactants, Collision/Activation Energy, and Products with particle diagrams; (2) a key and a Reaction Rate Graph; (3) seven numbered panels covering factors affecting reaction rate (increased temperature, increased concentration, greater surface area, and catalyst), plus a bottom flow diagram showing the chain: more successful collisions → more reactions occur → more products form → faster reaction rate. The catalyst panel includes an energy profile graph comparing reactions with and without a catalyst.
