Question

Collision Theory of chemical reaction is based on the:

• A. Potential Theory of gases
• B. Kinetic Theory of gases
• C. Molecular Theory of gases
• D. Theory of gases

Answer 1

The correct option is B Kinetic Theory of gases

The collision theory explains that gas-phase chemical reactions occur when molecules collide with sufficient kinetic energy. The collision theory is based on the kinetic theory of gases, therefore only dealing with gas-phase chemical reactions are dealt with.

The assumptions made in collision theory are:

1. All molecules are traveling through space in a straight line.
2. All molecules are rigid spheres.
3. The reactions concerned are between only two molecules.
4. The molecules need to collide.
