Collision frequency

Collision frequency is defined in chemical kinetics and collision theory, in the background of theoretical kinetics. Collision frequency is defined in chemical kinetics and collision theory, in the background of theoretical kinetics. For a reaction between A and B, the collision frequency (Z) is the number of collisions between A and B occurring in the container per unit volume per unit time. SI unit of Z is number of collision m − 3 s − 1 = 1000 N A   m o l   L − 1   s − 1 {displaystyle m^{-3}s^{-1}=1000N_{A} mol L^{-1} s^{-1}} , where N A {displaystyle N_{A}} is Avogadro constant.
