(a)
Interpretation:
The substance that flows across the membrane should be determined when 1.0 M NaCl solution is separated from a 1.5 M NaCl by a semipermeable membrane.
Concept introduction:
Osmosis is defined as the process wherein the water and small molecules are allowed to pass through a semi-permeable membrane, thus, converting the low solute concentration to a higher solute concentration. During this osmosis process, when the flow of additional solvent on one side of a semi-permeable membrane into a solution is prevented through pressure, then it is known as osmotic pressure.
Generally, osmotic pressure becomes higher when higher numbers of particles are dissolved and this is due to its colligative property. Thus, if two or more solutions having different concentrations are passed through the membrane along with pure water, then the flow of water will be from less concentrated solution in order to dilute the more concentrated solution.
(b)
Interpretation:
The direction of flow before and after achieving equilibrium across the membrane should be determined when 1.0 M NaCl solution is separated from a 1.5 M NaCl by a semipermeable membrane.

Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur).
