1.Radius of the molecule: As the radius of the molecule increases the space between the molecules decreases causing the number of collisions to increase, thus decreasing the mean free path.
2.Mean free path is the average distance a molecule travels, before colliding with another molecule. So, as the temperature increases Kinetic energy of the molecules increases Faster motion of molecules take place within the same time interval.Therefore, Mean free path increases with increase Temperature.
