Enthalpy of sublimation definition
WebEnthalpy of Atomization: In chemistry, the enthalpy of atomisation is the enthalpy change that accompanies the total separation of all atoms in a chemical substance. For example: atomization of methane molecule. CH 4 (g) → C (g) + 4H (g) Δ a H 0 = 1665.0 kJ mol -1. For diatomic molecules, the enthalpy of atomization is equal to the enthalpy ... WebEnthalpy of atomization is denoted by the symbol Δ at H. The enthalpy change of atomization of gaseous H 2 O is, for example, the sum of the HO–H and H–OH bond dissociation enthalpies .
