                Estimate the mean free path and collision frequency of a nitrogen molecule in a cylinder containing nitrogen at 2 atm. and temperature 17°C. Take the radius of a nitrogen molecule to be roughly  Compare the collision time with the time the molecule moves freely between two successive collisions, (Molecular mass of nitrogen  

Answer:

Here, P = 2 atm                                                                                                                                 Collision frequency = no. of collisions per second
