Consider a fluid layer A surrounded on both sides by a fluid, B. The fluid layer can be thought of as a membrane. A species S is diffusing across this membrane, and has concentrations c and c (in the fluid B) on the two sides of the membrane, as shown in Fig. 7.28. It often happens that the solubility of material S inside the membrane is different than its solubility in bulk solution B. We therefore define a partition coefficient k as concentration of S in material A (at equilibrium) (7.30) concentration of S in material B Hence k 1 means S is more soluble. Write down an expression for the flux across the membrane in terms of c, c, DA (diffusion coefficient of S in A) and Aya. Sketch the concentration profile. What is the effective diffusion coefficient value with partitioning, De?
In a cylinder of an automobile engine, immediately after combustion the gas is confined to a volume of 53.0 cm³ and has an initial pressure of 3.60 × 106 Pa. The piston moves outward to a final volume of 300 cm³, and the gas expands without energy transfer by heat. (Assume the gas in the engine is diatomic with y 1.40.)
