Collision Theory
• Molecules have to collide to break or bond
• Collisions happen a lot but few lead to reactions
• Factors of temperature (energy), frequency (concentration), and orientation
• Maxwell-Boltemann Distribution
o T2>T1
• Ea: minimum kinetic energy to break or form bonds
o No rxn if below Ea
• If concentration increases, rate increases
• Orientation determines what can or cannot collide
