Collision Theory

(Figure 19.1)

The colliding molecules must possess higher energy than the mean energy

Boltzman's energy distribution law:

The probability of a molecule possessing the threshold energy, E is proportional to exp

 

Conditions for chemical reactions to occur:
  • Suitable molecule must collide with each other
  • The molecules must collide with proper orientation (Determined by steric factor)
  • Colliding molecules must possess energy greater than the threshold energy(E).
