Find an expression for the rate of adsorption (d theta/dt)_ads, and an expression for the rate of desorption (d theta/dt)_des, where k_a and k_d are the adsorption and desorption rate constants, respectively. Using your result found in Step 2 above, show that at equilibrium theta = Kp/Kp + 1 Where K is the equilibrium constant for the adsorption/desorption process. FYI, this is called the Langmuir isotherm.

1.) (14 pts.) An extension of the Langmuir adsorption isotherm is when a catalyst has separate sites that selectively choose one material over another. An example of when this happens is the catalytic oxidation of H2S over a bed of iron oxide granules. The overall reaction is H2S + 12 02 → 2 S2 + H2O The proposed mechanism is provided on the following page where the reaction of the adsorbed O and H2S is the rate limiting step. H2S+S'...
