For an Na^+ --Cl^- ion pair, attractive and repulsive energies E_A and E_R, respectively depend on the distance between the ions r, according to E_A = - 1.436/r E_R = 7.32 times 10^-6/r^6 For these expression, energies are expressed in electron volts per Na^+ --Cl^- pair, and r is the distance in nanometers (nm). The net energy E_N is just the sum of the two expressions above. Determine the equilibrium spacing r_0 between the Na^+ and Cl^- Ions. 0) 0.68...
