Collision theory chemistry

Collision TheoryCollision Theory Collision Theory In order for a chemical reaction to take place, the reactants must collide. The collision transfers kinetic energy needed to break the necessary bonds so that new bonds can be formed. Atoms must be close together to form chemical bonds. This simple premise is the basis for a very powerful theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates. Collision theory is based on the following postulates: The rate of a reaction is proportional to the rate of reactant collisions:Collision Theory •The orientation of the colliding particles must favor the formation of the activated complex, in which the new bond or bonds are able to form as the old bond or bonds break. –Because the formation of the new bonds provides some of the energy necessary to break the old bonds, the making and breaking of Read Paper. Collision theory Collision theory is a theory proposed independently by Max Trautz in 1916 [1] and William Lewis in 1918, that qualitatively explains how chemical reactions occur and why reaction rates differ for different reactions.
