(3) A 0.35 mm diameter open tubular gas chromatography column is coated with stationary phase that is 0.25 im thick. The diffusion coefficient for a compound with a retention factor k 10 is D 1.5x10s m2 s' in the gas phase and D 2.5x10 m s' in the stationary phase. Calculate the plate height if the linear flow rate is 20 cm s. If you increase the temperature of this column what would happen to the plate height. Explain by giving reasons.
