enthalpy a2

Question 1

enthalpy change of hydration

Answer 1

enthalpy change that takes place when dissolving of 1 mol of gaseous ions in water to form 1 mol of aqueous ions under standard conditions (which can then form an ionic compound later)

Question 2

enthalpy change of solution

Answer 2

enthalpy change that takes place when 1 mole of a solute dissolves in a solvent
if solute is water, ions formed are aqueous.

Question 3

lattice enthalpy

Answer 3

the enthalpy change that occurs when 1 mole of an ionic compound/lattice is formed from its gaseous ions under standard conditions

Question 4

Boltzmann distribution curve

Answer 4

Spread of molecular energies in gases
