Collision theory chemistry

Collision theory chemistry is related to chemical kinetics science almost .
Collision theory chemistry is stated by Max Trautz and William Lewis in 1916 and 1918 .

collision theory chemistry useful :
In qualitative analysis Collision theory explains :
1-how chemical reactions occur .
2-why reaction rates differ for different reactions.

Mechanism of Collision theory chemistry:
Activation energy is The minimal amount of energy needed for reaction to occur .
activation energy released when Particles from different elements react with each other as they hit each other.

The collision is called successful if the elements react with each other , but if the concentration of at least one of the elements is too low, there will be fewer particles for the other elements to react with and the reaction will happen much more slowly.

Reaction becomes rapid in case of collision theory chemistry when:
1-when temperature increases, the average kinetic energy and speed of the molecules increases and this only increases slightly the number of collisions.
2-The rate of the reaction increases with temperature increase because a higher fraction of the collisions overcome the activation energy.
3-high concentrations .

Summary Collision theory chemistry:
when concentration of reactant is high ;and the temperature needed is high , then reaction speed increased more possible collisions occur between molecules , when the collisions is high and Activation energy increased this lead to transforming reactant molecules to products.

Thus collision theory chemistry is achieved
