Interpretation: For the given gases, Vander Waals constant (a) and the gas which showing strongest intermolecular attraction should be determined.
Concept introduction:
A modified ideal gas equation on account of molecular size and molecular interaction forces is termed as Van der Waals equation.
That is,
‘a’ and ‘b’ is called Van der Waals coefficient and are characteristic of the individual gas
Here,
- a is a measure of intermolecular attraction
- b is a measure of size of the molecule
Where,
P = pressure in atmospheres
V= volumes in liters
n = number of moles
R =universal gas constant (
T = temperature in kelvins

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). The formation of S2, AHF: S2 (g) = 535 kJ/mol. Compare the two values, and explain the difference. (8 points)arrow_forward
