Which of the following is a correct statement about collision theory? a. all collisions lead to chemical reactions. b. most collisions lead to chemical reactions. c. very few reactions involve particle collisions. d. effective collisions lead to chemical reactions. e. reactions do not require particles to collide.

The correct answer is option D.

Explanation:

The number of collisions that take place per second per unit volume of the reaction is called as collision frequency.

Particles undergoing only effective collision will lead to chemical reactions.

For a collision to be effective, the colliding molecules must have energy more than a particular value known as threshold frequency.

The factors which are responsible for the number of effective collisions are:

Hence, the correct answer is option D.
