Cards in this deck (10)
- 1Enthalpy of hydrationEnthalpy change when 1 mole of gaseous ions forms aqueous ions
- 2Lattice enthalpy of dissociationEnthalpy change when 1 mole of an ionic compound is separated into it's gaseous ions
- 3Lattice enthalpy of formationEnthalpy change to form 1 mole of an ionic substance from it's gaseous ions
- 4Mean bond dissociation enthalpyThe average enthalpy change to break the bond(s) in one mole of a substance/ molecules of a substance to form its gaseous atoms
- 5Electron affinityEnthalpy change when 1 mole of gaseous atoms forms 1 mole of gaseous negative ions
- 6Enthalpy of atomisationenthalpy change when 1 mole of gaseous atoms is formed from the element in it's standard state
- 7Perfect ionic modelIons are perfect spheres and the compound contains only electrostatic forces of attraction
- 8Enthalpy of formationEnthalpy change when 1 mole of a substance is formed from it's elements and all reactants and products are in their standard state
