What is Lattice enthalpy ? Give example. |
|
Answer» Solution :The lattice enthalpy of an ionic SOLID is defined as the energy required to COMPLETELY separate ONE mole of a solid ionic compound into GASEOUS constituent ions. Eaxmple : The lattice enthalpy of NaCl 788 kJ`mol^(-1) `. This means that 788, kJ of energy is required to separate one mole of solid NaCl into one mole of `Na_((G))^(+)` and one mole of `Cl_((g))^(-)` to an infinitie distance. |
