We can use the following equation to solve for ΔH˚rxn:
Balanced reaction: SO2(g) + 1/2 O2(g) → SO3(g)
You may want to reference (Pages 277 - 280)Section 6.9 while completing this problem.
Use standard enthalpies of formation to calculate H°rxn for the following reaction:
SO2(g) + 1/2 O2(g) → SO3(g)
