The difference between diffusion and effusion and Graham’s law in the form of an equation is to be explained. Concept Introduction: Graham law explains the phenomenon of diffusion and effusion in gaseous molecules. In diffusion, gaseous molecules are mixed with another gaseous molecule or intermingle with molecules of air because of their random motions. Effusion is the movement of gaseous molecules from system to vacuum through a small hole or a narrow space.

(a 4 shows scanning electron microscope (SEM) images of extruded actions of packing bed for two capillary columns of different diameters, al 750 (bottom image) and b) 30-μm-i.d. Both columns are packed with the same stationary phase, spherical particles with 1-um diameter. A) When the columns were prepared, the figure shows that the column with the larger diameter has more packing irregularities. Explain this observation. B) Predict what affect this should have on band broadening and discuss your prediction using the van Deemter terms. C) Does this figure support your explanations in application question 33? Explain why or why not and make any changes in your answers in light of this figure. Figure 4 SEM images of sections of packed columns for a) 750 and b) 30-um-i.d. capillary columns.³
