Work Produced by a Chemical Reaction

CHEM-LW1BXC

Calculate the work that can be produced in a hydrogen fuel cell per mol of gaseous $H_{2}$ at $25^{\circ} C$.

Use the following data:

$$\Delta H^{\circ}_{f}(H_{2}O) = -285. 8 \space kJ/mol$$
$$S^{\circ}(H_{2})=130.7 \space J/mol K$$
$$S^{\circ}(O_{2})=205.1 \space J/mol K$$
$$S^{\circ}(H_{2}O)=188.8 J/mol K$$

A

$-285.8 kJ/mol$

B

$1.30 \times 10^{4} kJ/mol$

C

$-341.7 kJ/mol$

D

$272.2 kJ/mol$
