Question

Which of the following is not true?

Reduction of the nitrogen in NO (to yield N2 and O2) is energetically favorable, but because the activation energy is high, the reaction must either be catalyzed or done at high temperatures to proceed at an appreciable rate.

Catalytic converters that reduce the nitrogen in NO can also reduce the sulfur in SO2, resulting in production of the toxic gas H2S when sulfur is present in the fuel.

Carbon-based compounds (usually CO and hydrocarbons) are reduced in a catalytic converter to yield CO2 and H2O.

CO and other incompletely oxidized forms of carbon are produced in greater quantities when gasoline is combusted with inadequate oxygen present.

Catalytic converters facilitate both oxidation and reduction reactions simultaneously.

Answer 1

Answer: carbon based compounds (usually CO and hydrocarbons) are reduced in a catalytic converter to yield CO2 and H2O.

A catalytic converter is present in vehicles to reduce the release of to IC gases from the burning of fuel. It consists of catalysts like nickel, platinum and paladium which catalyse redox reactions. NO is reduced to N2 and O2. CO and hydrocarbons are oxidised (not reduced ).
