The lattice energy of solid NaCl is 180 Kcal/mol. The dissolution of the solid in water in the form of ions is endothermic to the extent of 1kcal per mol. If the solvation energies of Na & Cl ions are in the ratio 6:5, the enthalpy of hydration of soduim ion is:
a)-85.6 Kcal/mol b)-97.5 Kcal/mol c) 82.6 kcal/mol d)100 Kcal/mol
Please post explanation also.
