In the preparation of $$HN{O_3},$$ we get $$NO$$ gas by catalytic oxidation of ammonia. The moles of $$NO$$ produced by the oxidation of two moles of $$N{H_3}$$ will be ________.
A.
2
B.
3
C.
4
D.
6
Answer :
2
Solution :
\[\underset{\left( \text{from air} \right)}{\mathop{4N{{H}_{3\left( g \right)}}+5{{O}_{2\left( g \right)}}}}\,\xrightarrow[500\text{ }K,\,9\text{ }bar]{Pt/Rh\text{ gauge catalyst}}\] \[4N{{O}_{\left( g \right)}}+6{{H}_{2}}{{O}_{\left( g \right)}}\]
Thus, 2 moles of $$NO$$ will be produced by the oxidation of 2 moles of $$N{H_3}.$$
