Estimate the time needed for a glycine molecule (see Table 13-4) to diffuse a distance of 25m
Question:
Estimate the time needed for a glycine molecule (see Table 13-4) to diffuse a distance of 25μm in water at 20°C if its concentration varies over that distance from 1.00mol / m3 to 0.50 mol / m3? Compare this "speed" to its rms (thermal) speed. The molecular mass of glycine is about 75 u.
