Standard enthalpy of formation of ethane
Webb22 mars 2024 · Abstract. High-level coupled cluster calculations obtained with the Feller–Peterson–Dixon (FPD) approach and new data from the most recent version of the Active Thermochemical Tables (ATcT) are used to reassess the enthalpy of formation of gas-phase C 2 H 2 O 4 (oxalic acid). The theoretical value was further calibrated by … WebbStandard Enthalpy of Formation. The standard enthalpy of formation, often referred to as the standard heat of formation, is the change in enthalpy of a particular compound during its formation (1 mole) from its constituent elements. The standard enthalpy of formation is most commonly expressed in units of kJ/mole or J/mole among others.
