Energetics

5. lattice enthalpy for an ion depends on its size and?
9. a chemical reaction which involves a decrease in Gibbs free energy
11. the unit of enthalpy (per mole)
13. solubility decreases down the group for these compounds
15. an enthalpy which requires energy to produce one mole of a gaseous atom from its elements under standard conditions
17. the distortion of an electron cloud on an anion in an ionic lattice
18. the energy exchange between a chemical reaction and its surroundings at constant pressure

1. solubility increases down the group for these compounds
2. an enthalpy change which requires energy to remove one mole of electrons from one mole of a gaseous, isolated, neutral atom
3. an enthalpy cycle used to calculate lattice energy'
4. a chemical reaction that releases energy to the surroundings
6. an enthalpy change where one mole of a specified gaseous ion dissolves in sufficient water to form a very dilute solution
7. the available energy to do useful work
8. a chemical reaction is not spontaneous if Gibbs free energy is?
10. an enthalpy change that takes place when 1 mole of an ionic solid dissolves in sufficient water to form an infinitely dilute solution.
12. a reaction where products react together to re-form reactants at the same time as the reactants are forming products
14. a thermodynamic quantity that represents the unavailability of a system's thermal energy for conversion into mechanical work
16. a regular repeated arrangement of alternating positive and negative ions in a crystal
