Chemical reaction starts when outside energy stretches, twists, or compresses molecule chemical bonds {initiation, reaction}.
energy
Energy typically comes from heat or light. Light adds electric energy and affects electrons directly. Heat makes molecules move faster with more kinetic energy, causing more and higher-energy molecule collisions.
size
In large molecules, collision is less likely to disrupt bond, because collision is more likely to hit other bonds.
shape
Molecule shape determines if collision affects bond. If collision is along bond line, bond disruption is more than if collision is from side.
charge
Bond disruption is greater if colliding atoms have opposite electric charges. Bond disruption is greater if colliding atoms have same electric-charge absolute value.
