$(i)$ and $(iii)$

Vedclass · Answer

(A) $1$. In the given reaction,$4 NH_{3} + 5 O_{2} \longrightarrow 4 NO + 6 H_{2}O$,the oxidation state of Nitrogen $(N)$ changes from $-3$ in $NH_{3}$ to $+2$ in $NO$ (oxidation).$2$. The oxidation state of Oxygen $(O)$ changes from $0$ in $O_{2}$ to $-2$ in $NO$ and $H_{2}O$ (reduction).$3$. Since both oxidation and reduction occur simultaneously,it is a redox reaction $(iii)$.$4$. This is also a displacement reaction $(i)$ because the oxygen atom displaces hydrogen from ammonia to form water.$5$. Therefore,the reaction is both a displacement reaction and a redox reaction.

The following reaction is an example of a:
$4 NH_{3}(g) + 5 O_{2}(g) \longrightarrow 4 NO(g) + 6 H_{2}O(g)$
$(i)$ displacement reaction
$(ii)$ combination reaction
$(iii)$ redox reaction
$(iv)$ neutralisation reaction
