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.
