Reactant A decomposes by three simultaneous reactions to form three products, one that is desired, B, and two that are undesired, X and Y. These gas-phase reactions, along with the rate laws, are as follows. (40pts) 1) A→X -r1A = rX= k1 = 0.0001 mol dm-3 sec-1 2) A→B -r2A = rB = k2 CA 2 = (0.0015 s-1 ) CA 2 3) A→Y -r3A=rY=k3 = 0.008 dm3 mol-1 sec-1 The specific reaction rates are given at 300 K and the activation energies for reactions (1), (2), and (3) are E1 = 10,000 kcal/mole, E2 = 12,000 kcal/mole, and E3 = 20,000 kcal/mole. (a) How, and under what conditions (e.g., reactor type(s), temperature, concentrations), should the reaction be carried out to maximize the selectivity of species B for an entering concentration of species A of 0.4 M and a volumetric flow rate of 2.0 dm3 /s? (b) Design the suitable type of reactor assuming there is no pressure drop.

The following reactions take place in a batch reactor: A+B--> C (desired product) B+C-->D (hazardous product) As the reaction proceeds, D builds up in the reactor and could cause an explosion if its concentration exceeds 15 mol/L. To ensure the safety of the plant personnel, the reaction is quenched (e.g., by cooling the reactor contents to a low temperature) and the products are extracted when the concentration of D reaches 10mol/L. The concentration of C is measured in real-time, and...
