Determine the Change in the Standard Entropy of the Universe $\frac { 1 } { 2 }$

question 113

Short Answer

Determine the change in the standard entropy of the universe for the given reaction from the given data.
H₂(g) + $\frac { 1 } { 2 }$
O₂(g) $\rightarrow$ H₂O(g) $\begin{array}{ccr} Substance&&S^{\circ}(\mathbf{J} /(\mathbf{m o l} \cdot \mathbf{K}))\\&\Delta H_{\mathrm{f}}^{\circ}\\& (\mathbf{k J} / \mathbf{m o l}) & \\ \mathrm{H}_{2}(g) & & 130.6 \\ \mathrm{O}_{2}(g) & & 205.0 \\ \mathrm{H}_{2} \mathrm{O}(g) & -241.8 & 188.7\end{array}$
