Chapter 2.10, Problem 19QP

(a)

To determine

Draw the graph showing the plotting of all three variables $E_N,E_R,\text{and}{E}_A$ respectively on a single plot.

(b)

To determine

From the graph part (a), find out the equilibrium spacing $\left(r_0\right)$ between ${\text{Na}}^{+}{\text{-Cl}}^{-}$ and the magnitude of the bonding energy $\left(E_0\right)$ between two ions.

c)

To determine

Refer to the values used in the Problem 2.18, mathematically find the $r_0\text{and}{E}_0$ respectively. After the results from mathematical calculation, compare the values of $r_0\text{and}{E}_0$ with the graphical results from part (b).
