Nitrate Enthalpy of Formation - Argonne National Laboratory

In chemistry and thermodynamics, the standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements in their reference state, with all substances in their standard states. The standard pressure value p = 10 Pa (= 100 kPa = 1 bar) is recommended by IUPAC, although prior to 1982 the value 1.00 atm (101.325 kPa) was used. There is no standard temperature. Its symbo… WebEnthalpy of formation is basically a special case of standard enthalpy of reaction where two or more reactants combine to form one mole of the product. Let us take an example of the formation of hydrogen bromide from hydrogen and bromine. H 2 ( g) + B r 2 ( l) → 2 H B r ( g) Δ r H ° = − 72.81 k J m o l − 1 WebEnthalpy of formation ( ΔHf) is the enthalpy change for the formation of 1 mol of a compound from its component elements, such as the formation of carbon dioxide from … port mor hotel
