Standard enthalpy of formation - Wikipedia

WebStandard Enthalpy of Formation. Standard enthalpy of formation is defined as the enthalpy change when one mole of a compound is formed from its elements in their most stable state of aggregation (stable state of aggregation at temperature: 298.15 K, pressure: 1 atm). For example formation of methane from carbon and hydrogen: WebCalculate the standard enthalpy of formation of gaseous carbon dioxide (CO2) using the following thermochemical information:. CH4(g) > C(s) + 2 H2(g) H = +74.8 kJ. CO2(g) + 2 H2O(l) > CH4(g) + 2 O2(g) H = +890.4 kJ. 2 H2O(l) >2 H2(g) + O2(g) H = +571.7 kJ WebThe NIST Chemistry WebBook (see link below) is an online resource that contains standard enthalpy of formation for various compounds along with the standard absolute entropy for these compounds from which the standard Gibbs free energy of formation can be calculated. ...
