s.) 7) The elementary reaction A+B → D is to be carried out to obtain a desired product (D). The rate constant for this reaction is k₁ = 150*exp(-5,000/T). Unfortunately, under conditions required for the reaction to occur, species B also undergoes a second-order decomposition to form an undesired product, B2U, with ry = k₂C, and k₂ = 300*exp(-2,000/T). 212 - a) What is the instantaneous selectivity for this system (SD/U)? Your answer must be simplified as much as possible. 4 Species: A, B, C, D, U YD = rD -VA ŶD= FD KD CA KU FAO-FA 4-02 b) Describe a reactor system (draw a schematic AND describe with words) and operating conditions you would use to maximize the selectivity to D.
