Question

In the following table are given the calculated mean free paths, collision diameters, and ratios of mean free path to collision diameter for four gaseous molecules all at the same temperature and pressure. Determine from this table what general relationship predicts the ratio of mean free path to collision diameter. Molecule Mean free path (m/collision) 1.1 x 107 4.2 x 10+ 7.2 x 10 9.1 x 10 Collision diameter (m) 2.7 x 10-0 4.5 x 10-10 H co, Ratio of mean free path to collision diameter 4.2 x 10 9.3 x 10 1.9 x 102 2.5 x 192 O A The smaller the molecule the larger the ratio of mean free path to collision diameter. [ Fullscreen 0 B The larger the molecule the larger the ratio of mean free path to collision diameter. lo 537 PM 2 A
