1). The gas phase reaction, N2 + 3 H?= 2 NH3, is carried out isothermally. The N? molar fraction in the feed is 0.2 for a mixture of nitrogen and hydrogen. Use: P = 12.4 Atm and T = 227 C. a) Which is the limiting reactant? b) Construct a complete stoichiometric table. c) What are the values of, CA°, 8, and ? d) Calculate the final concentrations of all species for a 60% conversion. 2). Determine which scheme is the most effective if you have a combination of 2 CSTR and a PFR reactors that achieve a total conversion equal to 80%. Assume that the first reactor of either kind reaches a 40% conversion. Use the following formulas to calculate the area under the -1/rA versus X curve: Rectangle CSTR-600 (X-1-X)² +250 (Xi+1-Xi) +600 Integral PFR = -500 (Xi+1-X)² + 100 (Xi-1-Xi) +500 Data: FA = 1 mol/s 3). For a plug-flow reactor you have the following data, X=0.4, molar flow rate of A (n^º) = 4 mol/min., Caº = 1 mol/l, k = 0.25 min¹. Assume first order reaction. a). Calculate the Volume for the PFR b). Calculate the conversion if you put 2 PFRs in series. 4). The gas phase reaction, N2O4 = 2 NO2, is carried out isothermally. The N?O4 molar fraction in the feed is 1. Use: P = 10 Atm and T = 227 C. a) Construct a complete stoichiometric table. b) What are the values of, CA°, 8, and e? c) Calculate the final concentrations of all species for a 80% conversion.
