Interpretation:
The standard enthalpy of formation
Concept Introduction:
The standard enthalpy of formation
Hess's law of constant heat summation states that the total enthalpy change for a given reaction can be expressed as a sum of the enthalpies of the intermediate reactions i.e.
Here, ΔH = total enthalpy change
ΔH1, ΔH2… ΔHn are the enthalpy changes of the intermediate steps.
