The Oxidation of Sulphur Dioxide to Sulphur Trioxide Is Important $\rarr$

The oxidation of sulphur dioxide to sulphur trioxide is important in the manufacture of sulphuric acid:
2 SO_{2 (g)} + O_{2 (g)} $\rarr$ 2 SO_{3 (g)}
Find the enthalpy change of this reaction given the following:
S _(s) + O_{2 (g)} $\rarr$ SO_{2 (g)} ; $\Delta$ H° = -296.83 kJ
2 S _(s) + 3 O_{2 (g)} $\rarr$ 2 SO_{3 (g)} ; $\Delta$ H° = -791.44 kJ
( $\Delta$ H_rxn = $\Delta$ H_products - $\Delta$ H_reactants; $\Delta$ H_rxn = Bond broken - Bonds made)

A) -197.78 kJ
B) 197.78 kJ
C) -485.23 kJ
D) 791.22 kJ
E) -1088.27 kJ
