Which of the following statements about the van Deemter equation H= A+ Blu+ Cu is incorrect? O A. The eddy diffusion term A is due to several paths through stationary phase. O B. A decrease in the linear velocity of the mobile phase u will increase the longitudinal diffusion. O C. An increase in the linear velocity of the mobile phase u will increase the eddy diffusion. O D. The longitudinal diffusion term B is due to mass diffusion in mobile phase. O E. The mass transfer term C is due to the slow rate of mass transfer between stationary and mobile phases.

Chapter 14, Problem 50 Carbon tetrachloride (CCI4) is diffusing through benzene (CgHs), as the drawing illustrates. The concentration of CCI, at the left end of the tube is maintained at 1.65 x 10-2 kg/m3, and the diffusion constant is 19.5 x 10-10 m2/s. The CCI4 enters the tube at a mass rate of 5.56 x 1013 kg/s. Using these data and those shown in the drawing, find (a) the mass of CCI4 per second that passes point A and (b) the concentration of CCl, at point A. 5.00 x 10-3 m Cross-sectional area = 3.00 x 10-4 m2
