Question

collision number definition

Answer 1

Thank you for asking this question. And let me help you in finding the right answer.

Collision number:

In Collision number we discuss about the collision density as well as the collision frequency. And It can be explaining in chemical kinetics in the background of the theoretical kinetics. It is denoted by Z. In Collision number we discuss about the average number of collisions between reacting molecules per unit of time per moles of reactant. 

Answer 2

"Collision number:

Collision number is defined as the "number of collisions" per unit time.

A collision is an interaction between two or more bodies in motion.

There is a large volume of atoms or molecules are involved in the collisions.

The collision number is indicated by the symbol of Z. When one molecule involved, the average number of collisions per unit time nearly one second per moles of reactant between reacting molecules is called collision number."
