The error in the argument that natural sources such as volcanoes add more chlorine to the stratosphere is to be explained. Concept Introduction: Ozone is a component of photochemical smog and is formed by the action of sunlight. Ozone in the troposphere is polluted, but in the stratosphere, it is a natural and essential part of our atmosphere. HCFCs and CFCs are a class of inert compounds of carbon, chlorine, and fluorine. They are quite useful for many applications. But the inertness of HCFCs has an environmental effect because of the presence of chlorine. However, due to the presence of hydrogen, they are more reactive and less environmentally degrading than CFCs.

(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

What impact (increase, decrease, or no change) does each of the following conditions have on the individual components of the van Deemter equation and consequently, band broadening? Increase temperature Longer column Using a gas mobile phase instead of liquid Smaller particle stationary phase Multiple Paths Diffusion Mass Transfer
