Chapter 11, Problem 11.93QP
Interpretation Introduction
Interpretation:
The volume of each atom and atomic radius (r) has to be calculated.
Concept introduction:
- Crystal structure: Crystal structure is arrangement of group of atoms or ions or molecule in the crystalline material.
- Unit cell: A simplest repeating unit in the crystal structure. Every unit cell is described in terms of lattice point. Example for unit cell: cubic, monoclinic, tetragonal, orthorhombic, rhombohedral, hexagonal and triclinic.

Using the following thermodynamic data, calculate the lattice enthalpy of lithium
oxide:
Li(g) → Li*(g) + e* AH₁= 540 kJ /mol
Li(s) → Li(g) AHS= +146 kJ/mol
O₂(s) → 20(g) AH₂= +488 kJ /mol
O(g) + 1e →→ O(g) AHA1= -142 kJ /mol
O` (g) + 1e¯ → 0²-(g) AHÃ₂= +844 kJ /mol
2Li(s) + 1/2O₂(g) → Li₂O(s) AH₁= -586 kJ /mol
