Problem
1. A rigid vessel initially contains 2 kmol of C and 2 kmol of O2 at 25oC, 200 kPa. Combustion occurs, and the resulting products consist of 1 kmol of CO2, 1 kmol of CO, and excess O2 at a temperature of 1000 K. Determine the final pressure in the vessel and the heat transfer from the vessel during the process.
2. Gaseous propane mixes with air, both supplied at 500 K, 0.1 MPa. The mixture goes into a combustion chamber, and products of combustion exit at 1300 K, 0.1 MPa. The products analyzed on a dry basis are 11.42% CO2, 0.79% CO, 2.68% O2, and 85.11% N2 on a volume basis. Find the equivalence ratio and the heat transfer per kmol of fuel.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
