Question

Give detailed account of collision theory of reaction rates of biomolecukar Gaseous reaction

Answer 1

Explanation:

Collision theory of reaction rates of bimolecular gaseous reactions-

This theory was proposed by Arrhenius and developed by Max Trautz and William Lewis to explain the rates of gaseous reactions.

It is based on the kinetic theory of gases.

According to this theory, the reactant molecules are assumed to be hard spheres.

Collisions must take place between reactants (molecules) to occur a reaction.

Collisions are possible if 2 or more molecules are present.

The minimum energy must be possessed by the reactant molecules to give products is called threshold energy

Molecules having other than threshold energy are called "normal molecules".

Collisions between normal molecules are called "normal collisions", which do not lead the chemical reaction, hence products are not formed.

In addition to the normal molecules, the molecules must aquire some extra amount of energy, called "activation energy"
