1. O'Hayre 11.7. Label the following processes and endothermic, exothermic, or neither: 1) oxidation of hydrogen fuel in a fuel cell, 2) steam reforming, 3) partial oxidation, 4) autothermal reforming, 5) water gas shift with steam at 600 psi and 400F, 6) natural gas compression, and 7) hydrogen expansion.

2. O'Hayre 11.11. Liquid petroleum gas (LPG) is a misture of gases primarily composed of propane (C3H8) and butane (C4H10). What is the overall steam reforming equation for propane? What is the steam to carbon ratio? What is the maximum hydrogen yield? How does this value for maximum hydrogen yield compare with the maximum hydrogen yield for the partial oxidation of propane in air (see reaction 11.13 in the book)?
