Kinetics of solute transport across a 2D monolayer. cout/cin is plotted as a function of time t, with A = 1 cm2, and V = 1 cm3 for (■) P2D = 10−5 cm s−1, and (▲) 10−6 cm s−1, and (•) P2D = 10−7 cm s−1, At short times (inset) where P2DAt/V « 1, the slope is P2DA/V and the rate constant can be obtained from kin,2D = P2DA.
