Question
Consider the reaction
Pure A is fed to a 1.0-dm3 CSTR where it reacts to form a desired product (D), which can then react further to produce an undesired product (U); both reactions are elementary and irreversible, and everything is liquid phase. The entering concentration of A is 1 mole/dm3 at a molar flow rate of 1 mol/min.
(a) Sketch the conversion of A, X, the instantaneous selectivity of D to U, SD/U, and the instantaneous yield of D, YD, as a function of space time (make sure to label them on the plot). You may want to write a sentence or two of reasoning for partial credit purposes.
(b) If at τ = 1.0 minutes the instantaneous selectivity, SD/U, is (1/2) and the conversion of A is (0.5),what are the specific reactions rates k1 and k2?

- 4. Ethylene oxide (C2H4O) can be produced by the partial oxidation of ethylene (C2H4) over a catalyst. An undesired side reaction is the complete oxidation of ethylene to CO2 and H2O. (R1) (R2) 2C2H4 + O2 → 2C2H4O C2H4 + 302 2CO2 + 2H2O The reactor is fed at 100 mol/hr of ethylene, and the molar feed rate of C2H4:O2 is 2:1. Air (79% N2 and 21% O2) is fed as the source of oxygen. 45% of the C2H4 is consumed in the reactor, and all of the O2 is consumed. What is the feed composition of all components in mol/hr?

- The process is to be designed for an 80% overall conversion of propane. The reaction products are separated into two streams: the first, which contains Hz gas, propylene (C3H6), and 0.5% of the propane that leaves the reactor, is taken off as product; the second stream, which contains the balance of the unreacted propane, 7% of the propylene in the product stream, and no H3, is recycled to the reactor. Calculate the flow rates and compositions of all streams and the single pass conversion of propane in the reactor.arrow_forwardUsing the tables in the pictures: Cyclobutane decomposes to ethylene according to the equation: C4H8(g) --> 2C2H4(g) Determine the order of the reaction and the rate constant, with units, based on the following concentration data.
