Question
Chapter 10, Problem 10.78SP
Interpretation Introduction
Interpretation:
Volume of SO2 produced from combustion of 1 kg coal that contains 2 % sulphur is to be calculated.
Concept introduction:
The expression to determine volume as per ideal gas equation is given as follows:
V=mRTPM
Where,
- R is gas constant.
- M denotes molar mass.
- m represents mass.
- V denotes the volume.
- T denotes temperature.
- P denotes the pressure.

32. 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

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.?
