Define : (a) Enthalpy of atomization (b) Enthalpy of vaporization |
|
Answer» (a) Enthalpy of atomization : The enthalpy change accompanying the dissociation of all the molecules in one mole of a gas phase substance into gaseous atom is called enthalpy of atomization. It is denoted by `Delta_("ato")H`. (b) Enthalpy of vaporization : The enthalpy change that accompanies the vaporization of one mole of liquid without changing its temperature at constant pressure is called enthalpy of vaporization. It is denoted by `Delta_("vap")H`. |
