New cards

Enthalpy of formation

Enthalpy change when one mole of a substance is formed from its constituent elements with all substances in their standard states

2
New cards

Enthalpy of combustion

Enthalpy change when one mole of a substance undergoes complete combustion in oxygen with all substances in their standard states

3
New cards

Enthalpy of neutralisation

Enthalpy change when one mole of water is formed in a reaction between an acid and an alkali under standard conditions

4
New cards

Ionisation enthalpy

  • First ionisation energy- enthalpy change when each atom in one mole of gaseous atoms loses one electron to form one mole of gaseous 1+ ions

  • Second ionisation energy-enthalpy change when each ion in one mole of gaseous 1+ ions loses one electron to form one mole of gaseous 2+ions

5
New cards

  • Electron affinity

First electron affinity- enthalpy change when each atom in one mole of gaseous atoms gains one electron to form one mole of gaseous 1- ions

Second electron affinity- enthalpy change when each ion in one mole of gaseous 1- ions gains one electron to form one mole of gaseous 2- ions

6
New cards

Enthalpy of atomisation

Enthalpy change when one mole of gaseous atoms is produced from an element in its standard state

7
New cards

Hydration enthalpy

Enthalpy change when one mole of gaseous ions become hydrated (dissolved in water)

8
New cards

Enthalpy of solution

Enthalpy change when one mole of an ionic solid dissolves in an amount of water large enough so that the dissolved ions are well separated and don’t interact with each other

9
New cards

Bond dissociation enthalpy

Enthalpy change when one mole of covalent bonds is broken in the gaseous state

10
New cards

Lattice enthalpy of formation

Enthalpy change when one mole of a solid ionic compound is formed from its constituent ions in the gas phase

11
New cards

Lattice enthalpy of dissociation

Enthalpy change when one mole of a solid ionic compound is broken up into its constituent elements in the gas phase

12
New cards

Enthalpy of vaporisation

Enthalpy change when one mole of a liquid is turned into gas

13
New cards

Enthalpy of fusion

Enthalpy change when one mole of a solid is turned into a liquid
