P10-4 B Consider the catalytic reaction as a function of the initial partial pressures 2AB+C The rate of disappearance of species A was obtained in a differential reactor and is shown below. (a) What species are on the surface? (b) What does Figure B tell you about the reversibility and what's adsorbed on the surface? (c) Derive the rate law and suggest a rate-liming step consistent with the above figures. (d) How would you plot your data to linearize the initial rate data in Figure A? (e) Assuming pure A is fed, and the adsorption constants for A and C are KA=0.5atm1 nd KC=0.25atm1 respectively, at what conversion are the number of sites with A adsorbed on the surface and C adsorbed on the surface equal? (Ans.: X=0.66 )
