The lattice energy of NaCl is 788 kJ mol-1. This means that 788 kJ of energy is required

Question

The lattice energy of NaCl is 788 kJ mol-1. This means that 788 kJ of energy is required (A) to separate one mole of solid NaCl into one mole of Na(g) and one mole of Cl(g) to infinite distance (B) to separate one mole of solid NaCl into one mole of Na(g)+ and one mole of Cl(g)- to infinite distance (C) to convert one mole of solid NaCl into one mole of gaseous NaCl (D) to convert one mole of gaseous NaCl into one mole of solid NaCl

Tardigrade Admin · Accepted Answer

Lattice energy is that amount of energy which is required to separate one mole of a solid into its constituents gaseous ions at infinite distances.

Since the lattice energy of

N a Cl

is

788 k J m o l^{- 1}

, it meas that

788 k J

of energy is required to separate one mole of solid

N a Cl

into one mole of

N a^{+} (g)

and one mole of

C l^{-} (g)

to infinite distance.
