(12 cards)
standard enthalpy change of formation
∆fH
the energy change when one mole of a compound is formed from its elements in their standard states under standard conditions
standard enthalpy change of atomisation
∆atH
the energy change to form one mole of gaseous atoms from the element in its standard state under standard conditions
first ionisation energy
∆IEH
the energy change when one mole of gaseous atoms loses one mole of electrons to form one mole of gaseous 1+ ions
first electron affinity
∆EAH
the energy change for one mole of gaseous atoms to gain one mole of electrons to form one mole of gaseous 1- ions
lattice enthalpy
∆LEH
the energy change to form one mole of an ionic compound from its gaseous ions under standard conditions
standard enthalpy change of solution
∆solH
the energy change when one mole of a solute dissolves completely in a solvent
enthalpy change of hydration
∆hydH
the energy change to dissolve gaseous ions in water to fork one mole of aqueous ions
when doing lattice enthalpy calculations with 1/2O2 what do you do to the O2 enthalpy values?
nothing!! the enthalpy values are PER ATOM
standard enthalpy change of combustion
energy change when one mole of a substance reacts completely with oxygen under standard conditions with all reactants and products being in their standard states
standard enthalpy change of a reaction
energy change that accompanies a reaction in the molar quantities expressed in a chemical equation under standard conditions with all reactants and products being in their standard states
standard enthalpy change of neutralisation
energy change that accompanies the reaction of an acid by a base to form one mole of H2O(l) under standard conditions with all reactants and products in their standard states
average bond enthalpy
breaking of one mole of bond in gaseous molecules
