Determine the expression for E, by substitut- ing to into Equation 2.17. 2.19 For an Na+-a-ion pair, attractive and repul- sive energies E, and Er respectively, depend on the distance between the ions r, according to P 2 1.436 EA E 2. 6 do 7.32 X 10 ER ps For these expressions, energies are expressed in electron volts per Na*--Clº pair, and r is the distance in nanometers. The net energy Ey is just se the sum of the preceding two expressions. (a) Superimpose on a single plot Ey, Er, and E, O versus r up to 1.0 nm. (b) On the basis of this plot, determine (i) the equilibrium spacing ?, between the Naº and C1 ions, and (ii) the magnitude of the bonding energy E, between the two ions. 2.2 (c) Mathematically determine the ro and E. val ues using the solutions to Problem 2.18. and com. pare these with the graphical results from part (b). 2.24 2.20 Consider a hypothetical X Yion pair for which the equilibrium interionic spacing and bonding en cray values are 0..38 nm and 5.37 eV, respectively Hill is known that in l.quation 2. 17 has a value of S. &
