Question

The following reaction is an example of a:

$4N{H}_3\left(g\right)$ + $5O_2\left(g\right)$$\to$ $4NO\left(g\right)$ + $6H_{2}O\left(g\right)$
(i) displacement reaction
(ii) combination reaction
(iii) redox reaction
(iv) neutralisation reaction

• A. (i) and (iv)
• B. (ii) and (iii)
• C. (i) and (iii)
• D. (iii) and (iv)

Answer 1

Answer: (C)

(i) and (iii)

$4N{H}_3\left(g\right)$ + $5O_2\left(g\right)$$\to$ $4NO\left(g\right)$ + $6H_{2}O\left(g\right)$ is an example of displacement as well as redox reaction. Oxygen displaces hydrogen of ammonia. Hence, this is a displacement reaction. Nitrogen of ammonia is getting oxidized with the addition of oxygen. This is also an example of redox reaction.
