Chapter 3, Problem 3.104CHP

Interpretation Introduction

Interpretation:

The total energy change during formation of chlorine sodide from sodiumand chlorinehas to be calculated and also the formation of sodium chloride is preferred over chlorine sodide has to be explained

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 (${\text{ΔH}}_{\text{f}}{}^{\text{0}}$)

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