Answers (1)
As we have learnt, Lattice energy is the energy required to completely separate one mole of solid ionic compound into its constituent gaseous ions.
As implied in the definition, this process will always be endothermic, and thus the value for lattice energy will be positive.
Hence, option number (2) is correct.
