Chapter 5.3, Problem 5.3.1SR

Interpretation Introduction

Interpretation:

The lattice energy of $\text{KF}$ has to be compared with $\text{LiF,KCl}\text{and}\text{KI}\text{.}$

Concept Introduction:

Lattice energy: The amount of energy required to convert a mole of ionic solid into their constituent ions in gaseous form.

Coulomb’s law: The electrostatic force of attraction or repulsion is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

$\begin{array}{l}\text{Coulomb's law: }\boxed{\text{F}\propto \frac{(+q)(-q)}{r^2}}\\ \text{where,q}\text{represent the charge of the ions}\\ \text{r represent the interionic distance}\text{. }\end{array}$
