Question

What is the drawback of Collision Theory?

Answer 1

Collision Theory: According to this theory, the reactant molecules are assumed to be hard spheres, and reaction is postulated to occur when molecules collide with each other.

Drawbacks of Collision Theory:

• This theory is only applicable to simple gaseous molecules.
• Collision theory does not explain energy activation barriers.
• This theory considers atoms/ molecules to be hard spheres and ignores the structural aspect of atoms/molecules.
• This theory is not applicable to reversible reactions.
