Link to Collision Theory Animation: http://www.kscience.co.uk/animations/collision.htm I. Rate of Reaction = how fast a reaction occurs
A. Examples:
slow reactions - rusting, rocks weathering
fast reactions - explosions, sodium in water, fuel burns in air with oxygen
B. Collision Theory: reactions happen when the reactants collide
II. Rate of Reaction Depends on 4 Things
A. Temperature (hotter = faster)
B. Catalyst (substance that makes a reaction faster without being used up)
C. Phase (gases are faster than liquids, liquids are faster than solids)
D. Concentration (more reactants = faster) |
