The parallel first-order reactions A → B,A → C have activation energies of 8 and 10 kcal/mole, respectively. In a 1 liter batch reactor at 100°C the selectivity to B is 50% and the conversion is 50% in a reaction time of 10 min with CAo = 1 mole/liter. The solvent is water and the reactor can be pressurized as needed to maintain liquids at any temperature.

(a) What temperature and reactor volume are required to produce 90% selectivity to B at 90% conversion in a CSTR using a feed of 2 molar A at a flow rate of 10 liters/min?

(b) What temperature and reactor volume are required to produce 90% selectivity to B at 90% conversion in a PFTR using a feed of 2 molar A at a flow rate of 10 liters/min?

1)The following are the steps for B-cell activation. The steps are in an incorrect order. 1. B cells display antigens in MHC class II receptors on the cell surface. 2. Antibodies released by plasma cells bind to antigen so they will be destroyed by other cells of the immune system. 3. B cells rearrange their DNA to create a unique B-cell receptor. 4. B cells become activated by interacting with helper T cells. 5. B cells undergo clonal expansion. 6....
