Surface Physics question.

  1. May 24, 2010 #1
    From the kinetic theory of gases, the rate of the number of gas molecules bombarding the unit area of a surface (Z) is given by,
    Z = P/(2mkT)1/2

    Consider a crystal inside a chamber containing nitrogen gas at pressure 10-10 torr and at room temperature (300K).

    Calculate the number of nitrogen molecules collected by unit area of the crystal per second. Assume that all colliding nitrogen molecules stick on the surface.

    [1 torr = 1.33 x 10-2 Ncm-2, Avogadro number: 6.03 x 1023 mol-1]
