Question: Which of the following options correctly describe lattice energy? select all that apply.
The following options correctly describe lattice energy:
- Lattice energy is the energy required to completely separate one mole of an ionic compound into its constituent ions in the gas phase.
- Lattice energy is a measure of the strength of the ionic bonds in an ionic compound.
- Lattice energy is typically expressed in kilojoules per mole (kJ/mol).
- Lattice energy is a positive value, indicating that it is an endothermic process to separate an ionic compound into its constituent ions.
- Lattice energy depends on the charges and sizes of the ions in the ionic compound.
Here are some additional details about each of these options:
- Lattice energy is the energy required to completely separate one mole of an ionic compound into its constituent ions in the gas phase. This is a very energy-intensive process, as it requires the strong ionic bonds between the ions to be broken.
- Lattice energy is a measure of the strength of the ionic bonds in an ionic compound. The higher the lattice energy of an ionic compound, the stronger the ionic bonds between the ions.
- Lattice energy is typically expressed in kilojoules per mole (kJ/mol). A kilojoule is a unit of energy equal to 1,000 joules. A mole is a unit of quantity equal to the number of atoms in 12 grams of carbon-12.
- Lattice energy is a positive value, indicating that it is an endothermic process to separate an ionic compound into its constituent ions. This means that energy must be supplied in order to separate an ionic compound into its constituent ions.
- Lattice energy depends on the charges and sizes of the ions in the ionic compound. The greater the charges of the ions and the smaller the sizes of the ions, the higher the lattice energy of the ionic compound.
