In an Experiment, 1 $\frac { 1 } { 2 }$

question 142

Multiple Choice

In an experiment, 1.00 atm of H₂(g) in a 10.0 L container at 25°C was reacted under standard state conditions with a stoichiometric quantity of O₂(g) to form water vapor:
H₂(g) + $\frac { 1 } { 2 }$ O₂(g) $\rightarrow$ H₂O(g) . What is the entropy change for the reaction? $$\begin{array} { l c } \text { Substance } & \boldsymbol { S } ^ { \circ } ( \mathbf { J } / \mathbf { m o l } \cdot \mathbf { K } ) \\\mathrm { H } _ { 2 } ( g ) & 130.58 \\\mathrm { O } _ { 2 } ( g ) & 205.0 \\\mathrm { H } _ { 2 } \mathrm { O } ( g ) & 188.83\end{array}$$

• B) -44.3 J/K
• C) -18.1 J/K
• D) +18.1 J/K
• E) +44.25 J/K
