96. Solving a chemistry problem

The determination of a mixture of organic substances was carried out on a chromatographic column 1 meter long by changing the flow rate. For 3 different speeds, the dead time of the column was 9, 5, 4 seconds, respectively. The retention time of dodecane was 1200, 660, 420 seconds, and the width of the peak at its base was 105, 59, and 28 seconds. Determine a) 3 carrier gas flow rates. b) the number of theoretical plates and HETP (H) c) the constants A, B, C in the Van Deemter equation.
