Question

Find the diffusion coefficient of nitrogen in standard condition, if the free path of the molecule is 1.6 × 10–8 m

Answer 1

Answer:

Estimate the mean free path and collision frequency of a nitrogen molecule in a cylinder containing nitrogen at 2.0 atm and temperature 17

o

C. Take the radius of a nitrogen molecule to be roughly 1.0 A. Compare the collision time with the time the molecule moves freely between two successive collisions (Molecular mass of N
