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?

An anasthesiologist is preparing to anesthetize a patient, who is undergoing surgery to remove her gallbladder. The anasthesia is accomplished with the administration of three drugs, primarily Midazolam (a non-opiod anesthetic), Fentanyl (an opiod analgesic), and gallamine (a long-acting muscle relaxant). Initially, each drug is contained seperate solutions in saline. The concentrations of each solution are 270 ng/mL midazolam, 3 ng/mL of fentanyl, and 42 mg/mL of gallamine. The three solutions are sent through a mixerbefore being delivered to the patient. Help the anasthesiologist plan the dosing rates if the mixed solution needs to be infused at 0.1 mL/min with 0.25 ng/mL of midazolam and 0.02 ng/mL of fentanyl.
A. Write a mass conservation equation for each component
B. Determine the mass flow rate of each drug solution into the mixer
C. Determine the weight fractions of gallamine and saline in the infusion stream

A spherical tank of diameter of 10 meters contains liquid toluene at 1 atmosphere at 25 oC. An initially filled tank is drained from the bottom such that the liquid level drops to half. As we drain the tank, toluene vaporizes. The enthalpy of vaporization of toluene at its normal boiling point, Tn =383.8 K, is 33.74 kJ/mol. Calculate the number of moles toluene evaporated from liquid to vapor phase. If the draining is isothermal, calculate the amount of heat provided by the atmosphere to the toluene in the tank.
