Question
Chapter 9.5, Problem 31PP
Interpretation Introduction
Interpretation : The percent yield of CO for the given reaction should be calculated.
Concept Introduction : The actual yield of the product is the amount of product which is formed at the end of reaction experimentally whereas theoretical yield represents the amount of product calculated by expecting that 100 % of reactant changes to product. The percent yield can be shown as:

34. Figure 3 shows Van Deemter plots for a solute molecule using different column inner diameters (i.d.).
A) Predict whether decreasing the column inner diameters increase or decrease bandwidth.
B) Predict which van Deemter equation coefficient (A, B, or C) has the greatest effect on increasing or
decreasing bandwidth as a function of i.d. and justify your answer.
Figure 3 Van Deemter plots for hydroquinone using different column inner diameters (i.d. in μm). The data was
obtained from liquid chromatography experiments using fused-silica capillary columns packed with 1.0-μm particles.

experimentally determined van Deemter plots of column efficiency, H, vs. flow rate. H is a
quantitative measurement of band broadening. The left plot is for a liquid chromatography application and the
night is for gas chromatography. Compare and contrast these two plots in terms of the three band broadening
mechanisms presented in this activity. How are they similar? How do they differ? Justify your answers.?
