WebMar 16, 2015 · 1 Answer. Sorted by: 3. Your approach to use Hess's Law is reasonable! Δ H r = − 680 − ( 715 + 2 ⋅ 158) = − 1711 k J ⋅ m o l − 1. That's the enthalpy for C F X 4 - a molecule with four C − F bonds. The average C − F bond enthalpy is smaller: 1711 4 k J ⋅ m o l − 1 ≈ 427 k J ⋅ m o l − 1. Share. WebSanjith Hegde123. Recall the definition of enthalpy change of formation. "The enthalpy change of a reaction where one mole of a substance is formed from its elements, where everything is in their standard states". So one mole of iron oxide is formed from its elements in its standard states. Use this information to write an equation...
