Q. In Ostwald process of manufacturing of HNO_{3} catalyst used is
A) MO
B) Fe
C) Mn
D) Pt
Explanation
(d)
Oswald process of manufacturing of HNO_{3}
4NH_{3}+5O_{2}$\overset{Pt}{\rightarrow}$4NO+6H_{2}O+heat
2NO+O_{2}$\overset{50℃}{\rightarrow}$2NO_{2}(g)
3NO_{2}+H_{2}O⟶2HNO_{3}+NO
$\therefore\$Pt is catalyst in Oswald process.
