1

Define Enthalpy change

The heat added to a system at a constant pressure

2

Define the standard enthalpy change of formation

The Enthalpy change when one mole of a substance is formed from it's constituent elements in their standard states under standard conditions.

3

Define the Enthalpy change of atomisation

This is the Enthalpy change to form one mole of atoms in the gas phase.

4

Define Enthalpy change of lattice formation

This is the Enthalpy change that occurs when one mole of an ionic compound is formed from the ions of the elements in the gas phase.

5

Define Enthalpy change of lattice breaking

This is the enthalpy change that occurs when one mole of an ionic compound is broken up into ions of the elements in the gas phase.

6

Define Enthaply change of hydration

This is the enthalpy change that occurs when one mole of gaseous ions is surrounded by water molecules to make a solution

7

Define Enthalpy change of solution

This is the enthalpy change that occurs when one mole of an ionic compound dissolves in water to form a solution.
