| Question | Answer |
|---|---|
| Enthalpy of atomization | the energy change required to change one mole of atoms from their standard state to a gaseous state. |
| Lattice enthalpy (dissociation) | The energy required to convert one mole of the solid compound into gaseous ions. |
| Enthalpy of solution | the energy change that occurs when one mole of substance dissolves in excess solvent. |
| Enthalpy of hydration | the energy change that occurs when one mole of gaseous ions are added to water to form a dilute solution. |
| Entropy (S) | the measure of the distribution of total available energy between the particles. |
| Gibbs free energy (G) | the energy available to do work. |
| Standard enthalpy change of formation (ΔH⁰f) | the enthalpy change that results when one mole of a compound is formed from its elements at 298.15 K and 1.00E5 Pa. |
| Standard enthalpy change of combustion (ΔH⁰C) | the enthalpy change that results when one mole of a compound reacts with oxygen at 298.15 K and 1.00E5 Pa |
