Chapter 12.3, Problem 3RC

Interpretation Introduction

Interpretation:

The lattice enthalpy of sodium iodide should be calculated.

Concept introduction:

The lattice enthalpy is calculated by using following method,

${\text{ΔH}}^{\text{o}}{}_{\text{f}}\text{(NaI)}\text{=}\text{ΔH at(Na)}\text{+}\text{ΔH at(I)+}{\text{ΔH}}_{\text{IE}}\text{(Na)}{\text{+ΔH}}_{\text{EA}}\text{(I)+}\text{ΔH}{}_{\text{lattice}}\text{(NaI)}$
