Which constituents of NaCl are mentioned as being separated to an infinite distance when calculating its Lattice Enthalpy?
Options
- ANa+ and Cl- to a finite distance
- BNa+ to an infinite distance and Cl- to a finite distance
- CCl- to an infinite distance and Na+ to a finite distance
- DBoth Na+ and Cl- to an infinite distance
Correct answer
D. Both Na+ and Cl- to an infinite distance
Step-by-step solution
The Lattice Enthalpy of NaCl is defined as the energy required to separate one mole of solid NaCl into one mole of Na+ (g) and one mole of Cl- (g) to an infinite distance.
