Show transcribed image text For an ion pair of Potassium Chloride (KC), K'-CT, attractive and repulsive energies E and ER, respectively, depend on the distance between the ions r, according to: YR 1.63 fH expressions, energies are expressed in electron volts (eV) per K'-CI pair, and r is the distance in nanometers (nm). The net energy Ex is just the sum of the two expressions above. (a) Use a computer software (excel) to superimpose on a single plot EN, ER, and EA versus r up to 1,0 nn(similar to Figure 2.10b). The r-values should vary from 0.15 to 1.0 with 0.001 increment. (20 points) (b) On the basis of this plot, determine (i) the equilibrium spacing ro between the K and Cl- ions, and (ii) the magnitude of the bonding energy Eo between the two ions. (4 points)
