Question

Write any two criteria for effective collision.

Answer 1

Collision: Two objects coming towards each other with some momentum and then coming in contact with each other is known as a Collision.

Explanation:

1. According to the collision theory, the molecules must collide with enough energy, known as the activation energy, to prevent the chemical bonds from breaking, in order for a chemical reaction to occur.
2. Additionally, the molecules must collide in the proper orientation.
3. If these two requirements are satisfied, a collision is referred to be a successful collision or an effective collision. The frequency of the effective collisions is equal to the rate of a chemical reaction.

Criteria for effective collision.

1. The frequency of collision.
2. The effective fraction of collisions.
