An inventor has developed a device that at steady state

Chapter 13, Problem 13.89

(choose chapter or problem)

An inventor has developed a device that at steady state takes in liquid water at \(25^{\circ} \mathrm{C}\), 1 atm with a mass flow rate of 4 kg/h and produces separate streams of hydrogen (\(\mathrm{H}_{2}\)) and oxygen (\(\mathrm{O}_{2}\)), each at \(25^{\circ} \mathrm{C}\), 1 atm. When the device operates isothermally at \(25^{\circ} \mathrm{C}\), the inventor says it requires an electricity input of 237,180 kJ per kmol of hydrogen produced. Heat transfer with the surroundings occurs, but kinetic and potential energy effects can be ignored. Evaluate the inventor’s claim.
