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. What is the optimal flow rate of the orange curve? ( 3 pts) e. Which curve will have minimal band broadening at ( 3 mathrm{~mm} / mathrm{s} ) ? ( ( 2 mathrm{pts} ) )
