Question

the number of particles crossing a unit area perpendicular to x axis in unit time is given by n = -D(n2-n1/x2-x1) where n1 and n2 are number of particles per unit volume for the values of x meant to be x1 and x2 find the dimension of the diffusion constant D​

Answer 1

Explanation:

The number of particles is given by

crossing a unit area perpendicular to X - axis in unit time , where

are particles per unit volume for the value of

meant to

. Find the dimensions of

called diffusion constant.
