The enthalpy of vaporization ΔH v a p and the enthalpy of sublimation ΔH s u b need to be calculated from the given data Concept Introduction: Vaporization and sublimation are phase transition reactions which involve a change in the state of a substance from the liquid to the vapor/gas phase and from the solid to the gas phases respectively Enthalpy changes associated with the reaction is essentially the amount of heat energy required for the phase transition. These are denoted as ΔH v a p for vaporization and ΔH s u b for sublimation. The relationship between pressure (P), temperature (T) and the enthalpy change ( ΔH) is given via the Clausius-Clapeyron equation: lnP = − ΔH R ( 1 T ) + C -----(1) Where R = 8.314 J/mol-K and C is a constant.
