Applications of the First Law B. A. Rowland 53750/53760 Types of Enthalpies You will need to be able to classify certain types of enthalpy reaction, and be able to give an example of each: H rxn = The Enthalpy of Reaction : the enthalpy for any given chemical reaction. H c = The Enthalpy of Combustion : the enthalpy for any given combustion (oxygen is always a reactant) reaction. H f = The Enthalpy of Formation : The enthalpy for any given reaction in which only the component elements in their standard states appears on the reactant side, and only 1 mole of product appears on the product side. For phase changes: H vap = The Enthalpy of Vaporization : the enthalpy for any given vaporization (substance going from liquid to gas) reaction. H fus = The Enthalpy of Fusion : the enthalpy for any given fusion (substance going from liquid to solid) reaction. H sub = The Enthalpy of Sublimation : the enthalpy for any given sublimation (substance going from solid to gas) reaction. The Enthalpy of Condensation: H cond = - H vap The Enthalpy of Melting: H melt = - H fus The Enthalpy of Deposition: H dep = - H sub Further discussion on Enthalpy: For a given chemical reaction, A + 2B --> C, H rxn = -100 kJ/mol. What if I wanted the enthalpy of reaction for C --> A + B?
