Question

In the ostwald’s process, nitric acid is prepared by the catalytic oxidation of :

• A. N2
• B. NH3
• C. N2O5
• D. NO2

Answer 1

Answer: (B)

NH3

Answer 2

Reaction invole in ostwald's process:

4NH3(g) + 5O2(g) $\underset{5atm,850^{0}C}{\overset{\quad Pt/Rhcatalyst\quad}{\rightarrow}}$ 4NO(g) + 6H2O(g)

NO + 1/2O2 $\longrightarrow$2HNO3

+ NO
