Question

Which of the following statement is incorrect about the collision theory of chemical reaction?

• A. It considers reacting molecules or atoms to be hard spheres and ignores their structural features.
• B. Number of effective collisions determines the rate of reaction
• C. Collision of atoms or molecules possessing sufficient threshold energy results into the product formation.
• D. Molecules should collide with sufficient threshold energy and proper orientation for the collision to be effective.

Answer 1

Answer: (C)

Collision of atoms or molecules possessing sufficient

threshold energy results into the product formation.

Answer 2

Not only sufficient threshold energy of colliding atoms or molecules but also the proper orientation for the collision is required for the formation of products.
