Interpretation: The enthalpy change of the
Concept Introduction: Hess’s law states that the overall change in enthalpy for the solution is the sum of all changes independent of the different phases or steps of a reaction.
Answer to Problem 38LC
Thus, the enthalpy change in kJ for the reaction
Explanation of Solution
The chemical reaction for which enthalpy change is to be calculated
Enthalpy changes for the combustion of aluminum and iron are
To get the given chemical reaction, we have to reverse the reaction
Now add the two reactions
