Collision theory
In Collision theory, the rate of a reaction generally depends on two factors namely, energy and orientation factors.
Sometimes, certain reactions which are highly exothermic do not proceed.
This means that the reactants have sufficient activation energy to make the collisions effective. However, they still do not proceed at a given temperature because the reactant molecules are not properly oriented at the time of the collisions.
All energetically effective collisions do not result in a chemical change. For example, the formation of methanol from bromoethane depends upon the orientation of the reactant molecules as shown below:
CH3Br+OH−→CH3OH+Br−
The proper orientation of the reactant molecules leads to bond formation whereas, improper orientation makes them simply bounce back, and no products are formed.
