Answer 2

Answer:

The molar lattice energy of an ionic crystal can be expressed in terms of molar lattice enthalpy, pressure, and change in volume via the following equation:

ΔGU = ΔGH – pΔVm

Where:

ΔGU denotes the molar lattice energy.

ΔGH denotes the molar lattice enthalpy.

ΔVm is the change in volume (per mole).

p is the pressure.

Therefore, the outer pressure is also considered when calculating the lattice energies of ionic solids.
