1. The elementary gas-phase reaction A+B+2C is carried out in a packed-bed reactor. The entering molar flow rates are FA-5 mol/s, F-2 FAO, and Fr-2FAO, with CA0-02 mol/dm³. The entering temperature is 325 K. Additional Information: CPA CPI CIC 20 cal/mol/K, k-0.0002 dm/(kg-mol-s) @ 300K CP-20 cal/mol/K, a-0.00015 kg¹, E-25 kcal/mol AHR -20 kcal/mol @298K, Ke-1000@ 305K (a) Write the mole balance, the rate law, Kc as a function of T, k as a function of T, and CA, CBI, Ce as a function of X, p, and T. (b) Write the rate law as a function of X, p, and T. (c) Show the equilibrium conversion is 3K X₂ = 3KG 2.2K (K-1) 2(K-1) and then plot Xe vs. T. (d) What are e, Cpi, ACP? (e) Write the energy balance for adiabatic operation. (f) Plot and then analyze Xe, X, p, and T versus W when the reaction is carried out adiabatically. Describe why the profiles look the way they do.
