2. Postulate a catalytic mechanism for catalyst A. To accomplish this task, it may be useful to try to view individual events and answer individual questions with the simulation module, such as:

a. How does CO adsorb? Molecularly or dissociatively? Can you visualize the adsorption event? Describe it in words.
b. How does O2 adsorb? Molecularly or dissociatively? Can you visualize the adsorption event? Describe it in words.
c. Can you visualize the surface reaction happening? (You may need to slow down the simulation delay to “see” this happen.) Describe it in words.
d. Show, by way of derivation, how this mechanism leads to the same rate law equation, with the same concentration dependence, as in problems #1. Be sure to state all assumptions that you make during your derivation.
e. Compare your catalytic mechanistic model to the simulation data you collected for one case (one set of reactant concentrations) of CO oxidation on catalyst A at 600 K. Regress and compare parameters (kinetic, thermodynamic) as part of your comparison.
