Use the standard reaction enthalpies below to determine ?H?rxn for the reaction
8 SO3(g) ?S8(s) + 12 O2(g) ?H?rxn = _______ kJ
8 SO2(g) ? S8(s) + 8 O2(g) ?H?rxn = +2374 kJ
2 SO2(g) + O2(g) ?2 SO3(g) ?H?rxn = ?198 kJ
Report your answer without units and in scientific notation with three significant digits.
