Question

Catalytic convertor brings about

• A. Complete oxidation of hydrocarbons
• B. Oxidation of carbon monoxide to carbon dioxide
• C. Reduction of nitrogen oxide to nitrogen
• D. All of the above

Answer 1

The correct option is D All of the above

The catalytic converter is used to convert toxic and harmful pollutant into less toxic emission before they are released in the atmosphere from the engine of motor vehicles. The catalytic converter works as two types- reduction catalyst and the oxidation catalyst. The catalyst is a substance that causes or accelerates a chemical reaction without being unaffected.

The catalytic converter reduces carbon monoxide hydrocarbon and nitrous oxides.

(A) The oxidation catalyst reduces the carbon monoxide by oxidizing by reacting carbon monoxide with oxygen in exhaust gas forming carbon dioxide.

(B) The oxidation catalyst burns the hydrocarbons and aids the reaction with leftover oxygen in the exhaust.

(C) The reduction catalyst separates nitrogen atom out of nitrous oxides and freezes oxygen, the nitrogen atom combines with another nitrogen atoms forming nitrogen.

Hence, the correct answer is 'All of the above'
