(a) Make a graph showing the retention time of each peak in Figure 24-25 in chromatograms B, F, and C as a function of position along the line BC. Predict the retention times for solvent compositions midway between B and F and midway between F and C. Draw a stick diagram (representing each peak as a vertical line) of each of the two predicted chromatograms.
(b) What would be the solvent compositions midway between B and F and midway between F and C?
