How fast or slow a reaction occurs
Temperature, pressure, concentration
Surface area and catalysts
Collision theory
Increases - particles move faster, collide more often
Increases rate - particles closer, more collisions
Increases rate - more particles, more collisions
Only surface particles can collide with reactants
Break into smaller pieces or crush to powder
More exposed particles → faster reaction
Surface AreaVolume\frac{\text{Surface Area}}{\text{Volume}}VolumeSurface Area
Provide alternative pathway with lower activation energy
No - remain unchanged after reaction
