MCQ

उत्तर

(i) and (iii)

Explanation - 

In the following reaction, `4"NH"_3("g") + "SO"_2 -> 4"NO"("g") + 6"H"_2"O"("g")`

Hydrogen is getting displaced from NH3 by O2 to form NO hence, this is an example of a displacement reaction. At the same time, the addition of oxygen to a compound is called oxidation So, NHis getting oxidised to NO. Addition of hydrogen to a compound is called reduction so, Ois reduced to H2O. Since both, the process of oxidation and reduction are happening at the same time this reaction is also an example of a redox reaction.
