We can use the following equation to solve for ΔH˚rxn:
Note that we need to multiply each ΔH˚f by the stoichiometric coefficient since ΔH˚f is in kJ/mol.
Also, note that ΔH˚f for elements in their standard state is 0.
4 FeO(s) + O2(g) → 2 Fe2O3 (s)
calculate the value of ΔH°rxn for each of the following reactions.
