Thermodynamics Flashcards
what is enthalpy of lattice formation
Standard enthalpy change when 1 mole of an ionic crystal lattice is formed from its constituents ions in gaseous form
what is enthalpy of lattice dissociation
Standard enthalpy change when 1 mole of an ionic crystal lattice form is separated into its constituents in gaseous form
what is the enthalpy change of formation
Energy transferred when 1 mile of the compound is formed from its elements under standard conditions ( 298k and 100kpa) , all reactants and products being in their standard states
what is enthalpy of atomisation
Is the enthalpy change when 1 mole of gaseous atoms is formed from the element in its standard states
what is bond dissociation enthalpy
Standard molar enthalpy change when one mole of a covalent bond is broken into two gaseous atoms
what is the first ionisation enthalpy
Enthalpy change required to remove 1 mole of electrons from 1 mole of gaseous atoms to form 1 mole of gaseous ions with a +1 charge
second ionisation enthalpy
the enthalpy change to remove 1 mole of electrons from one mole of gaseous +1 ions to produce one mole of gaseous 2+ ions
what is the first electron affinity
Enthalpy change that occurs when 1 mole of gaseous atoms gain 1 mole of electrons to form 1 mole of gaseous ions with a -1 charge
what is the second electron affinity
the enthalpy change when one mole of gaseous 1- ions gains one electron per ion to produce gaseous 1- ions
what is enthalpy change
heat energy at constant pressure
