Calculate the Standard Entropy Change for the Following Reaction,
2 $\to$

Calculate the standard entropy change for the following reaction,
2 SO₂(g) + O₂(g) $\to$ 2 SO₃(g)
Given S ^$\circ$ [SO₂(g) ] = 248.2 J/K.mol,S ^$\circ$ [O₂(g) ] = 205.1 J/K.mol,and S ^$\circ$ [SO₃(g) ] = 256.8 J/K.mol.

B) -94.0 J/K·mol-rxn
C) -187.9 J/K·mol-rxn
D) +187.9 J/K·mol-rxn
E) +196.5 J/K·mol-rxn
