Resistance to Mass Transfer in the Stationary Phase A c. The van Deemter plot to the right shows the band broadening for three columns with different size stationary phase particles ( (1.8 mu mathrm{m}, 3 mu mathrm{m} ), and ( 5 mu mathrm{m}) ). On the plot, label which curve corresponds to each particle size. Justify your choice using at least one term on the van Deemter equation. (5 pts) d.
