Chapter 12, Problem 8E

Interpretation Introduction

Interpretation:

The solution becomes hot when lithium iodide was dissolved in water. Based on the given information given questions are to be answered.

Concept introduction: The heat of solution is the sum of enthalpy of solute and enthalpy of hydration. It is calculated by the formula,

  ${\text{ΔH}}_{\text{soln}}={\text{ΔH}}_{\text{solute}}+{\text{ΔH}}_{\text{Hydration}}$

To determine: The process is endothermic or exothermic, the relative magnitudes of the lattice energy of lithium iodide and its heat of hydration, qualitative energy diagram for the dissolution of $\text{LiI}$ and the driving force of the process.
