For the gas phase irreversible catalytic reaction is given below A+B The reaction was carried out in a differential reactor to which A, B, and C were fed together Run Number PA (atm) 0.1 1 10 3 4 00 ya NH PB (atm) 1 10 1 20 20 1 1 20 Pc (atm) 2 2 2 2 10 2 2 Reaction rate (mol (gcats) 0.073 3.42 0.54 6.80 288 0.56 034 4.5 1 20 1 1 (a) Sketch (-1A) as a function of PA, as a function of Ps, and as a function of Pe. (b) From your observations in part a, which species would appear in the numerator of the rate expression? Which species would appear in the denominator of the rate expression? (c) From your conclusions from part b. suggest a rate law consistent with the experimental data (d) From your rate expression, which species can you conclude are adsorbed on the surface? (e) From your conclusions in part d, suggest a mechanism and rate limiting step for this reaction. (1) Show succinctly using, sketches, graphs, outlines how you would evaluate the rate law parameters to obtain mol k=4.75 atm 8 cats K = 825 ca , K -24 de (g) For an entering partial pressure of A of 2 atm in a reactor, what is the ratio of sites of A to C sites at 80% conversion of A? (h) At what conversion are the number of A and C sites equal?
