This bonus question is worth 4 points and is set to 0 points in Canvas. If correct, I will add the points to your overall grade after review. Skipping it will not affect your Test 3 grade. Bonus 1 Use the standard enthalpy of formation (ΔH°f) values and the standard enthalpy of reaction (ΔH°rxn) given below to calculate the standard enthalpy of formation of SO₂(g). 2 SO₃(g) + 2 H₂(g) → 2 SO₂(g) + 2 H₂O(g) ΔH°rxn = −198 kJ ΔH°f values: SO₃(g): −396 kJ/mol H₂O(g): −242 kJ/mol What is ΔH°f for SO₂(g)?
