In the van deemter equation, plate height (H) = A + B/u+ Cu. So, A, B, U, and C affects the plate height. A is the eddy diffusion term, B is the longitudinal or ordinary diffusion term, C is the nonequilibrium or resistance to mass transfer coefficient, and U is the linear velocity.
<u>Competition</u> describes an interaction in which two organisms that interact must use the same limited resources because they are competing for them.
