Chapter 3, Problem 3.91SP

Interpretation Introduction

Interpretation:

The Born-Haber cycle for formation of lithium fluoridehas to be drawn.

Concept introduction:

Born-Haber cycle:

Born-Haber cycle determines the energy of a reaction. It deals with reactions between metals and halogen or non-metals leads to form ionic compounds. There are few steps to form a ionic compound and it is mentioned below

1. 1. Electron affinity(EA)
2. 2.  Ionization energy(IE)
3. 3. Sublimation energy (${\text{ΔH}}_{\text{sub}}$)
4. 4. Bond dissociation energy (${\text{ΔH}}_{\text{diss}}$)
5. 5. Lattice energy(U)
6. 6. Net energy (${\text{ΔH}}_{\text{f}}{}^{\text{0}}$)

${\text{ΔH}}_{\text{f}}{}^{\text{0}}\text{=}{\text{ΔH}}_{\text{sub}}\text{+}\text{IE}\text{+}{\text{ΔH}}_{\text{diss}}\text{+}\text{EA}\text{+}\text{U}$
