You may want to reference (Pages 186 - 190)Section 5.7 while completing this problem.
Given 2 SO2(g) + O2(g) → 2 SO3(g), which of the following equations is correct?
(a) ΔH˚f[SO3] = ΔH˚rxn – ΔH˚f[SO2]
(b) ΔH˚f[SO3] = ΔH˚rxn + ΔH˚f[SO2]
(c) 2ΔH˚f[SO3] = ΔH˚rxn + 2ΔH˚f[SO2]
(d) 2ΔH˚f[SO3] = ΔH˚rxn – 2ΔH˚f[SO2]
(e) 2ΔH˚f[SO3] = 2ΔH˚f[SO2] – ΔH˚rxn
