. Elementary biophysics: selected topics. Biophysics. x3/4 xl/4. x3/4 •r1/4 Fig. 37. The initial arrangement has all the particles in one half of the setup. The concentration, plotted on the right, is 100% up to the division point, then falls abruptly to zero. After a short time there is a net flow of particles to the right, so that the concentration now drops more gradually to zero. After more time for diffusion, the particles have reached almost to the right-hand end of the tube, and the concentration falls almost linearly to zero. After an infinite time the particles are evenly distributed

The concentration, plotted on the right, is 100% up to the division point, then falls abruptly to zero. After a short time there is a net flow of particles to the right, so that the concentration now drops more gradually to zero. After more time for diffusion, the particles have reached almost to the right-hand end of the tube, and the concentration falls almost linearly to zero. After an infinite time the particles are evenly distributed through the tube which is twice as large as the starting tube, so the concentration throughout is half the starting concentration. The positions in the tube at which the concentration is 75% or 25% of the starting value are indicated. The distance between these two points is a direct measure of the time elapsed since diffusion Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Epstein, Herman T.
