Enthralphy changes Flashcards
enthalpy change of (formation)
The enthalpy change of formation is the enthalpy change when 1 mole of substance is formed from its constituent elements with all substances in their standard states
enthalpy change of (combustion)
The enthalpy change when 1 mole of a substance undergoes complete combustion in oxygen with all substances in their standard states.
enthalpy change of(neutralization)
The standard enthalpy change of neutralization is the enthalpy change when solutions of an acid and an alkali react together under standard conditions to produce 1 mole of water.
enthalpy change of (Ionization)
First ionization enthalpy. The enthalpy change when one mole of gaseous atoms forms one mole of gaseous 1+ ions and one mole of electrons.
enthalpy change (electron affinity)
enthalpy change when one mol of gaseous atoms gains one electron to form one mol of -1 ions.
enthalpy change of (atomization)
enthalpy change when one mol of gaseous atoms is formed from its standard states.
enthalpy change of (hydration)
enthalpy change when one mole of gaseous ions become hydrated (dissolve in water)
enthalpy change of (solution)
enthalpy change when one mol of Ionic solid dissolves in an amount of water sufficient enough so that the dissolved ions are well separated and do not interact with each other.
bond enthalpy
enthalpy change when one mol of covalent bonds is broken in the gaseous state.
lattice enthalpy of formation
enthalpy change when one mol of a solid Ionic compound is formed from its constituent ions in the gas phase.
enthalpy change of ( vaporization)
enthalpy change when one mol of liquid is turned into gas.
enthalpy change of (fusion)
enthalpy change when one mol of a solid is turned into a liquid.
