The ionisation energy of potassium is 4.34 eV and the electron affinity of chlorine is 3.61 eV.
The Madelung constant for the KCl structure is 1.748 and the closest distance between ions of opposite sign is 0.314 nm.
On the basis of these data, calculate the cohesive energy of KCl. Compare this with the observed cohesive energy of 6.42 eV for the ion pair and comment on the reasons for any discrepancy
H2 has equilibrium bond length of 0.751 Å and bond dissociation energy of 432 kJ mol21, whereas F2 has equilibrium bond length of 1.417 Å and bond dissociation energyof 155 kJ mol21. On the same graph show qualitativesketches of the effective potential energy curve Veff for anH2 and an F2 molecule. In your solution, show the conversion from kJ mol21to the energy of a single molecule.1
