Most modern catalytic converters in automobiles have a surface with a platinum-rhodium catalyst. For which of the following reactions is this catalyst used? a. the conversion of nitric oxide into elemental nitrogen and oxygen gas
b. the conversion of carbon dioxide into bicarbonate
c. the conversion of carbon monoxide into carbon dioxide
d. the conversion of octane into carbon dioxide and water vapor

a. the conversion of nitric oxide into elemental nitrogen and oxygen gas.

Explanation:

Hello,

In this case, combustion at the automobiles' motors is not complete since gasoline usually has a considerable nitrogen oxides content (NOx) which is highly toxic when giving off from the cars. For that reason, recent advancements have shown platinum-rhodium-based catalytic converters have the capacity to catalyze the conversion of nitrogen oxides to elemental nitrogen and oxygen which are nontoxic. For that reason, answer is a. the conversion of nitric oxide into elemental nitrogen and oxygen gas.
