c. What is the maximum conversion that can be achieved in a 105 dm' CSTR?

7. When phase I is in equilibrium with phase II and phase II is in equilibrium with phase III, phase I must be in equilibrium with phase III. (True or False?)

8. A PFR operating isothermally at 773 K is used to conduct the following elementary reaction: A →＞ B+ C. If a feed of pure A enters at 5 atm and at a flow rate of 0.193 f'/s, what length of pipe with a cross-sectional area of 0.0388 f is necessary for the reaction to achieve 90% conversion? Data: & = 7.80 x 10' exp[-19,200/T] sl.

a. What are the PFR and CSTR volumes necessary to achieve 40% conversion?

b. Over what range of conversion would the CSTR and PFR reactor volume be identical?

d. What conversion can be achieved if a 72 dm? PFR is followed in series by a 24 dm3 CSTR?

a. Derive the rate expressions for this mixed-parallel series-reaction network and the expression for the percent selectivity to the epoxide (EP), namely, Sep = rEP/(rEp + ICD).

b. Calculate the maximum epoxide selectivity (Sepmar) attained.

a. How many   immiscible liquid phases   are there in this system at the bubble point?

b. Please determine the mole fraction of B in vapor phase at the bubble point.Note: A, B, and C may or may not be miscible in liquid phase. You can assume Raoult's Law applies for any homogeneous liquid mixture that may exist in this system. Your answer should be based on the calculation. A random guess will get no credit.

12. A rigid box of a volume of 1 m3 contains 1 mole of nitrogen at T = 300 K. The box is connected to ahigh-pressure nitrogen gas line at P = 200 kPa and T = 280 K via a valve. The valve is opened and one mole of nitrogen flows into the box. The valve is then closed. The process mentioned above occurs in a very short time, and the temperature of the box increases during this process.Then heat exchange occurs between the box and the surroundings (which are also at 300 K), and thetemperature of the box returns to 300 K.   Please calculate how much heat is exchanged between the box and the surroundings.  Note: You can assume nitrogen behaves like an ideal gas with Cp of 29 J/(mole K) under all conditions.
