Reaction Kinetic : 11.2 Collision Theory and Transition State Theory
Ø Collision theory
- Reaction is result from colliding particles with a certain frequency and minimum energy
- The collision which produces a reaction is called effective collision
Ø Effective collision
The collision which occur when the following condition is fulfilled:
- Colliding molecules posses minimum energy which is equal or more than the activation energy
- The reactants molecules collide at correct orientation
Ø Activation energy
The minimum amount of energy required to initiate a chemical reaction
Ø Transition state
Temporary state formed by reactant molecules as a result of collisions to form products.
Characteristics of transition state :
- Exist momentarity (temporary)
- High-energy (potential energy higher than that of reactant and products
- unstable
