Chapter 9, Problem 9.15QP

(a)

Interpretation Introduction

Interpretation:

The change in energy of ionic bond between $A^{+}$ and $B^{-}$ ions affected by doubling the radius of cation $A^{+}$ has to be explained.

Concept Introduction:

Coulomb’s law states that,

“The magnitude of electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitude of the charges and inversely proportional to the square of the distance between the point charges.”

It is represented as,

$F=k_e\frac{q_1{q}_2}{r^2}$

Where,

$\begin{array}{l}{k}_e=Coulomb\text{'}s\text{constant}\\ q_1,q_2=\text{point charges}\\ \text{r}=\text{distance of separation between the charges}\end{array}$

(b)

Interpretation Introduction

Interpretation:

The change in energy of ionic bond between $A^{+}$ and $B^{-}$ ions affected by tripling the charge on cation $A^{+}$ has to be explained.
