XVI11-4.—K cess specific heat arising from the ordered state, in units of Nk, as function of temperature.

XVII-1. Adsorption of N2 on rutile temperatures indicated are in degrees Kelvin. .

XVII-12. Isopotential contours.

XVII-13. Variation of the density with the adsorbed phase according to the potential theory.

XVII-15. Characteristic isotherm for nitrogen at 78 K on various solids

XVII-17. Schematic phase diagram for O2 on graphite

XVII-18. Contours of constant adsorption energy for a krypton atom over the basal plane of graphite. The carbon atoms are at the centers of the dotted triangular regions. The rhombuses show the unit cells for the graphite lattice and for the commensurate adatom lattice.

XVII-20. Isosteric heat of adsorption of Xe on a stepped Pd surface 8

XVII-21. Continued

XVII-22. Isosteric heats of adsorption for Kr on graphitized carbon black. Solid line

XVII-23.

XVII-25. Interaction energy distributions for N2 on BN

XVII-26. The arrangement of

XVII-27. Nitrogen adsorption at 77 K for a series of M41S materials. Average pore diameters

XVII-28. Hysteresis loops in adsorption.

XVII-29. Nitrogen isotherms the volume adsorbed is plotted on an arbitrary scale. The upper scale shows pore radii corresponding to various relative pressures. Samples

XVII-3. Langmuir isotherms.

XVII-30. Adsorption of Na on a silica gel at 77.3 K, expressed as a u- plot, illustrating a method for micropore analysis.

XVII-31. Copyright 1987, American Chemical Society.

XVII-4. Langmuir plus lateral interaction isotherms.

XVII-4.—Gibbs free energy for solids and liquid as function of concentration, for different temperatures, in a system with almost mutually insoluble solids.

XVII-5. Schematic detector response in a determination of nitrogen adsorption and desorption. A flow of He and N2 is passed through the sample until the detector reading is constant the sample is then cooled in a liquid nitrogen bath. For desorption, the bath is removed.

XVII-6.—Equilibrium between NaCl mid water.

XVII-7 shows the arrangement of the reactor building and the turbine generator building. Figure XVII-8 presents the plant layout.

XVII-7. Brunauer s five types of adsorption isotherms.
