The elementary, irreversible gas-phase reaction

A B + C

Is carried out adiabatically in a PFR packed with a catalyst. Pure A enters the reactor at a volumetric flow rate of 20 dm³/sec, at a pressure of 10 atm, and a temperature of 450 K.

Additional information:

C_PA = 40 J/molK C_PB = 25 J/molK C_PC = 15 J/molK

H_A = -70 kJ/mol H_B = -50 kJ/mol H_C = -40 kJ/mol

All heats of formation are referenced to 273 K.

With E = 31.4 kJ/mol

1. Plot and then analyze the conversion and temperature down the plug-flow reactor until and 80% conversion (if possible) is reached. (The maximum catalyst weight that can be packed into the PFR is 50 kg.) In other words plot X and T vs. catalyst weight. Assume the DP = 0.0.
