Consider the overall reaction AB C A possible catalyst material contains two different types of reactive sites, X and Y. Both A and B adsorb on X and Y, but the reaction proceeds only if A adsorbs on X and B absorbs on Y. This reaction is described by the following mechanism: (1) A+ X=A X (2) A YAY B+X BX B YBY (3) (4) A XBY C + X + ¥ (5) (a) What is the production rate of C if Reaction 5 is irreversible and Reactions 1-4 reach equilibrium? Hint: you can assume you know the monolayer coverage amounts of both the X and Y available sites, 0mx and emY (b) If the equilibrium constants for Reactions 1-4 are of the same order of magnitude, what happens to the production rate of C if very large or very small ratios of A to B are fed to the reactor? Why?
