Calculate the reactor volume required to achieve 90% conversion in an isothermal PFR for the 2nd order irreversible reactions, 2A — В + С The feed consists of pure A at a molar flow rate of 1.2 mol/s. The reaction rate constant is 6.7 mol/s-m-³ bar2. The pressure of the reactor is 1.4 bar at the inlet, falling linearly with reactor length, to 1.0 bar at the outlet. The reactor is of uniform cross-sectional area.

Consider the following potential energy diagram: * 1 p Reaction A Reaction B potential potential energy energy Reaction Pathway Reaction Pathway Reaction A is exothermic while Reaction B is endothermic Reaction A is endothermic while Reaction B is exothermic Reaction A will most likely be spontaneous while Reaction B is unlikely to be spontaneous O Reaction A releases heat while Reaction B absorbs heat

(Value of universal gas constant R= 1.987 cal/gm mole.)

In a batch reactor, a substance A was processed, which generated different products (D and U), through competitive parallel reactions with the following reaction kinetics: After 20 minutes of reaction, it was determined that the composition of the reaction medium was CA = 1 mol/L, CD = 5 mol/L, CU = 2 mol/L. The option that indicates, respectively, the instantaneous and global selectivities at the end of the reaction are: A) 3 and 2. B) 2.5 and 2. C) 2 and 3. D) 2 and 2.5.

Follows an elementary rate law and is carried out isothermally in a flow system. Theconcentrations of the A and B streams are 2M before mixing. The volumetric flow rate ofeach stream is 5 dm3/min and the entering temperature is 300K. The streams are mixedimmediately before entering. Two reactors are available. One is a 200 dm3 CSTR that canbe heated to 77 °C or cooled to 0 °C, the other is a 800 dm3 PFR operated at 300 K thatcannot be heated or cooled. Note that k = 0.07 dm3/mol min at 300 K and E = 83.7 kJ/mola) Which reactor and what conditions do you recommend? Explain the reason of yourchoice (space available, operational complexity). Back up your reasoning with theappropriate calculations b) How long would it take to achieve 90% conversion in a 200 dm3 batch reactor withinitial concentrations CA0 = CB0 = 1M after mixing at a temperature of 77 °C?

5. [ , The isothermal and isobaric gas phase reaction: A → 2B follows an elementary rate law. The rate constant k = 1.5 s' when the reaction temperature is at T = 350 K. Pure A is fed into a continuous-stirred tank reactor (CSTR) at a volumetric flow rate of 5 dm/s. What conversion of A can the reactor achieve if the reactor has a volume of 20 dm?

The elementary gas-phase reaction A → 3B is carried out in a cylindrical batch reactor divided by a thin metallic membrane into two compartments of equal volume, as shown in the figure below. Pure A Pure I Initially one side is filled with pure 'A', and the other with an inert gas T. Both sides are at the same pressure (1 atm.), the same temperature, and contain the same number of moles. The reaction is carried out isothermally and the rate constant for the reaction is 0.1 min. a. After 10 minutes the membrane ruptures. What is the pressure differential rating of the membrane? What is the conversion at this time? b. If the mixture continues to react after the membrane is ruptured, how much longer does it take for the conversion to reach 90% (based on the initial moles of A)? c. Sketch the pressure versus time behavior for the entire duration. Mark all the important values on your diagram.
