Applying the Second Law to Reacting SystemsSeparate
Chapter 13, Problem 86P(choose chapter or problem)
Separate streams of hydrogen (\(\mathrm{H}_{2}\)) and oxygen (\(\mathrm{O}_{2}\)) at \(25^{\circ} \mathrm{C}\), 1 atm enter a fuel cell operating at steady state, and liquid water exits at \(25^{\circ} \mathrm{C}\), 1 atm. The hydrogen flow rate is \(2 \times 10^{-4} \mathrm{kmol} / \mathrm{s}\). If the fuel cell operates isothermally at \(25 ^{\circ} \mathrm{C}\), determine the maximum theoretical power it can develop and the accompanying rate of heat transfer, each in kW. Kinetic and potential energy effects are negligible.
