WebMar 26, 2024 · If a nitrogen molecule with a diameter of about d = 370 pm (this corresponds to a collision cross section of σ = 4.3·10-19 m²) and a temperature of T=293 K and a pressure of p=1 bar is considered, a mean free path of λ = 67 nm results. In this case, the mean free path is about 10 times less than the wavelength of visible light! Webmethod mentioned in the previous chapter 2.1.2. We know the value n and obtain the size d of the molecule by means of equ. (2.15). Gas kinetic diameters obtained from the mean free path l are given below and compared with the values obtained from the covolume, cf. chapter 2.1.1: Molecule Kinetic diameter d/Å Covol.-diameter d/Å H2 2,3 2,76 O2 ...

Kinetic diameter is a measure applied to atoms and molecules that expresses the likelihood that a molecule in a gas will collide with another molecule. It is an indication of the size of the molecule as a target. The kinetic diameter is not the same as atomic diameter defined in terms of the size of the atom's … See more Collisions between two dissimilar particles occur when a beam of fast particles is fired into a gas consisting of another type of particle, or two dissimilar molecules randomly collide in a gas mixture.
