The diffusion coefficient depends on the physical propeies of the paicle and the membrane through which it is diffusing. In general, the larger the diameter of the paicle, the slower the rate of diffusion. Increasing temperature will increase the rate of diffusion. Ref: Katzung B.G. (2012). Chapter 1. Introduction.
