Question

define collision diameter and collision number?

Answer 1

Hello mate,

Here is your answer,

The distance between the centers of two molecules taking part in a collision at the time of their closest approach is called collision diameter.

Collision number refers to collision density or collision frequency. It is defined in chemical kinetics in the background of theoretical kinetics. Its symbol is Z. It is the average number of collisions between reacting molecules per unit of time per moles of reactant.

HOPE THIS HELPS UU :)

AND STAY BLESSED.

Answer 2

collision diameter

the distance between the centers of two colliding molecules when at their closest point of approach.
