The wall collision frequency, it is desired to find the frequency Z with which the molecules in an ideal gas strike a unit area of a wall from one side only. The gas is at rest and at equilibrium with a temperature T and the number density of the molecules is n. All molecules have a mass m. All molecules in the region x 0 will hit an area S in the yz-plane in a short time ?t if they are in the volume Sux?t. The number of wall collisions per unit area per unit time will be verify the above development.
