1. The catalytic activity of zeolites can be affected by: a. The Si/Al ratio b. The size of pore windows and cages in the zeolites C. The nature of substituted cations d. All of the above 2. The figure on the right shows TPD spectra for Nz desorption from Rh (100) from different initial coverages. We can infer that: Ny/Rh(100) 0.33 ML a. Nitrogen desorption follows second-order kinetics b. Nitrogen desorption follows first-order kinetics C. Nitrogen desorption rate is independent of surface coverage d. There are four different adsorption sites 0.23 ML 0.14 ML why 0.04 ML vi 600 700 800 900 1000 3. The highlighted crystallographic plane is: a. hep (1010) b. hcp (1101) C. hcp (1101) d. hcp (1011) ro a 4. Crystallographic planes with high surface energy: a. Are always catalytic sites of high activity b. Are usually weak adsorption sites C. Are prevalent in catalytic particles d. Can reconstruct to reduce the surface energy 5. A method that identifies crystalline phases in the bulk of a sample is: a. X-Ray Diffraction (XRD) b. Energy-Dispersive X-Ray analysis (EDX) c. X-Ray Photoelectron Spectroscopy (XPS) d. All of the above
