Hello Ariana! Molecular weight and diffusion are inversely proportional; the greater the molecular weight, the slower the rate of diffusion. In fact, certain molecules can never pass through membranes, thus protecting the cell. I am not sure I understand your theory and second question.
Here, is the diffusion coefficient matrix, () is the thermal diffusion coefficient, is the body force per unite mass acting on the ith species, = / is the partial pressure fraction of the ith species (and is the partial pressure), = / is the mass fraction of the ith species, and â = â =
