Summary:
For Reaction #1 (SO2 is product) _ Sorxn = - 84.611 J/K
For Reaction #2 (SO3 is the product) _ Sorxn = - 836.931 J/K
As predicted they are both negative, but Rxn #1 is close to zero, and we would also predict that it would be close to zero, since the number of moles of gaseous molecules did not change from reactant to product.
