Into a combustion reactor, hexane at 55 mol and 25% excess dry air are fed. The fractional conversion of hexane is 85%. Assume that air is 21 mol% oxygen and 79 mol% nitrogen. The governing equation for the combustion reaction is: 2 C6H14 + 19 O2 → 12 CO2 + 14 H2O a. Draw a complete flowchart of the process. Clearly state any assumptions. b. Perform a degree-of-freedom analysis (atomic species DOF). c. What is the mole fraction of carbon dioxide in the flue gas on a dry basis? PLEASE Solve using ATOMIC SPECIES, thank you

Pure CO is mixed with 100 percent excess air and completely burned at constant pressure. The reactants are originally at 400 K. Determine the heat added or removed if the products leave at 600 K. The standard heat of reaction at 298 K is -282.99 kJ per mol CO burned. The mean specific heats applicable in the temperature range of this problem are 29.10, 29.70, 29.10, and 41.45 J/mol K respectively for CO, O₂, N₂ and CO₂.

CH-13 Ammonia is produced by the following reaction N2+3 H2= 2 NH3 In a commercial process for ammonia production, the feed to an adiabatic reactor contains 1 kmol/s of nitrogen and stoichiometric amount of hydrogen at 700 K. What is the maximum allowable conversion in the reactor, if the adiabatic temperature rise across the reactor should not exceed 100 K. Assume the feed and product streams to be ideal gas mixture. reaction at 700 K for the above reaction is calculated to be 94.2 kJ/mol. Mean molar heat capacities (Cp), in the range 700 – 800 K, are 0.03, 0.0289 and 0.0492 kJ/mol K for nitrogen, hydrogen and ammonia, respectively. The heat of
