Back to paper

Which of the following statements are true based on the 4NH3(g)+5O2(g)→4NO(g)+6H2O(g)?
(a) N gets oxidized
(b) O gets oxidized
(c) N gets reduced
(d) O gets reduced  

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. (a) and (d).

 

The correct statements are:

  • (a) N gets oxidized: In the reaction, the oxidation state of nitrogen increases from -3 in NH3 to +2 in NO. This increase in oxidation number indicates oxidation.
  • (d) O gets reduced: The oxidation state of oxygen decreases from 0 in O2 to -2 in both NO and H2O. This decrease in oxidation number signifies reduction.
