For the reaction 2H₂(g) + O₂(g) → 2H₂O(g), what is the standard entropy change, $$\Delta S^\text{o}_{\text{rxn}}$$, given the following standard absolute entropies? $$S^\text{o}(\text{H}_2) = 130.7\ \text{J}/(\text{mol} \cdot \text{K})$$, $$S^\text{o}(\text{O}_2) = 205.1\ \text{J}/(\text{mol} \cdot \text{K})$$, and $$S^\text{o}(\text{H}_2\text{O(g)}) = 188.8\ \text{J}/(\text{mol} \cdot \text{K})$$
