Calculate `DeltaH^(0)` for `2Al_((s))+Fe_(2)O_(3)rarr2Fe_((s))+Al_(2)O_(3)` given that standard enethalpy of `Fe_(2)O_(3)` and `Al_(2)O_(3)` are -196.5 and -399.1 K.cal

Explanation

To calculate the standard enthalpy change (ΔH°) for the reaction:

\[ 2 \text{Al}_{(s)} + \text{Fe}_2\text{O}_3 \rightarrow 2 \text{Fe}_{(s)} + \text{Al}_2\text{O}_3 \]

we will use the standard enthalpies of formation for the reactants and products.
