The elementary gas-phase reaction A B + 2C is carried out isothermally in a flow reactor with no pressure drop.

The specific reaction rate at 50oC is 104 min1 and the activation energy is 85 kJ/mol. Pure A enters the reactor at 10 atm and 127oC and a molar flow rate of 2.5 mol/min. Calculate the reactor volume to achieve 90% conversion in: (a) a PFR (b) a CSTR (c) Pressure drop. Plot the conversion (X) and pressure (P) as a function of the PFR volume when = 0.001 dm3. What are X and P at V = 500 dm3? (d) Assume that the reaction is reversible with Kc = 0.025 mol2/dm6, and calculate the equilibrium and conversion. (e) redo (a) to achieve a conversion that is 90% of the equilibrium conversion for reversible reaction from (d). (f) redo (b) to achieve a conversion that is 90% of the equilibrium conversion for reversible reaction from (d). (g) redo (c) for reversible reaction from (d).
