Multiple Choice
The diagram below shows the activity of cerium oxides that have been proposed as catalytic materials to reduce emissions of nitrogen monoxide, carbon monoxide, soot, and hydrocarbons during the combustion of diesel fuel. Based on the diagram, if the reactions are irreversible, which of the following does NOT illustrate a function of the cerium oxide catalyst? 
A) 2 NO + 2 Ce2O3 → 4 CeO2 + N2
B) CO2 + Ce2O3 → 2 CeO2 + CO
C) C4H10 + 2 O2 + 18 CeO2 → 9 Ce2O3 + 4 CO2 + 5 H2O
D) C + 4 CeO2 → 2 Ce2O3 + CO2
