Some chemical reactions proceed by the in it ial loss or transfer of an electron to a diatomic species. Which of the molecules N2, NO. O2, C2, F2, and CN would you expect to be stabil ized by (a) the addit ion of an electron to form AB-. (b) the removal of an electron to form AB+?
Without stratospheric ozone (O₃), harmful solar radiation would cause gene alterations. Ozone forms when the bond in O₂ breaks and each O atom reacts with another O₂ molecule. It isdestroyed by reaction with Cl atoms formed when the C−C lbond in synthetic chemicals breaks. Find the wavelengths oflight that can break the C−Cl bond and the bond in O₂.
Consider a hypothetical ionic compound AB (comprised of A+ and B- ions). Given the following enthalpy data and using a Born-Haber cycle calculation, predict ΔHlattice in kJ mol-1. A(s) + B(s) → AB(s) ΔrH = -449 kJ mol-1 A(s) → A(g) ΔrH = 113 kJ mol-1 B(s) → B(g) ΔrH = 92 kJ mol-1 First ionization energy of A(g) = 529 kJ mol-1 Electron affinity enthalpy of B(g) (exothermic) = -345 kJ mol-1

(a) The ionization energy of potassium (K) is 4.34 eV and the electron affinity of chlorine (Cl) is -3.61 eV. The Madelung constant for the KCl structure is 1.748 and the distance between ions of opposite sign is 0.314 nm. On the basis of these data only, compute the cohesive energy of KCl per ion pair. (b) The observed cohesive energy of KCl is 6.42 eV per ion pair. On theassumption that the difference between this figure and that obtained in (a) is due to the exclusion principle repulsion, find the exponent n in the formula Br^-n for the potential energy arising from this source.
