Problem 4 30 Points Experimental Data For The Gas Phase Catalytic Reaction A B Is Shown Below The Limiting Step In 1 (58.28 KiB) Viewed 15 times

Problem 4 (30 points) Experimental data for the gas-phase catalytic reaction: A+B → is shown below. The limiting step in the reaction is known to be irreversible, so that the overall reaction is irreversible. The reaction was carried out in a differential reactor to which A, B, and C were all fed. Run Number PA (atm) PB (atm) Pc (atm) Reaction rate (mol)/(g-cats) 1 2 3 1 1 10 1 1 20 0.1 1 10 1 20 20 1 1 2 2 2 2 10 2 2 0.114 1.140 0.180 2.273 0.926 0.186 0.0243 5 6 7 a (a) Suggest a rate law consistent with the experimental data. (b) For an entering partial pressure of A of 2 atm in a PBR, what is the ratio of A to C sites at 70% conversion of A? c) What catalyst weight is necessary to achieve 85% conversion of A for a stoichiometric feed, flow of A of 2 mol/s and entering partial pressure of A of 2 atm? If necessary, feel free to use any of the following parameter values: k= 2.5 mol 2 atm g-cates KA = 4 atm-, Kc = 13 atm-1 .
