What is the standard enthalpy of formation of Fe2O3?
People also ask, what is the standard enthalpy change of formation of iron III oxide?
If the products end up with less stored energy than the reactants, the enthalpy change will be negative (exothermic). The heat of formation for iron(III) oxide is -826 kJ/mol.
Similarly, which of the following defines the heat of formation of Fe2O3 s )? Fe2O3 (s) + 2Al (s) -> Al2O3 (s) + 2Fe (l) ΔH= -800.3 kJ/mol If the standard heat of formation of Al2O3 (s) is -1675.7 kJ/mol and the heat of fusion for iron (Fe (s) -> Fe(l)) is 5.2 kj/mol, determine the standard heat of formation of Fe2O3 (s).
One may also ask, what is the enthalpy of formation of Al2O3?
Vibrational and/or electronic energy levels.
Enthalpy of formation of solid at standard conditions (nominally 273.15 K, 1 atm.)
|ΔfH°solid (kJ/mol)||-1675.7 ± 1.3|
How do you find the standard enthalpy of formation?
This equation essentially states that the standard enthalpy change of formation is equal to the sum of the standard enthalpies of formation of the products minus the sum of the standard enthalpies of formation of the reactants. and the standard enthalpy of formation values: ΔH fo[A] = 433 KJ/mol. ΔH fo[B] = -256 KJ/mol.
