Question: Which of the following reactions is a part of the large scale industrial preparation of nitric acid?
A) $\mathrm{Cu}\left(\mathrm{NO}_3\right)_2+2 \mathrm{NO}_2+2 \mathrm{H}_2 \mathrm{O} \underset{500 \mathrm{~K}, 9 \text { bar }}{\stackrel{\mathrm{Pt}}{\longrightarrow}} 4 \mathrm{HNO}_3+\mathrm{Cu}$
B) $\mathrm{NaNO}_3+\mathrm{H}_2 \mathrm{SO}_4 \underset{500 \mathrm{~K}, 9 \text { bar }}{\stackrel{\mathrm{Pt}}{\longrightarrow}} \mathrm{NaHSO}_4+\mathrm{HNO}_3$
C) $4 \mathrm{NH}_3+5 \mathrm{O}_2$ (from air) $\underset{500 \mathrm{~K}, 9 \text { bar }}{\mathrm{Pt}} 4 \mathrm{NO}+6 \mathrm{H}_2 \mathrm{O}$
D) $4 \mathrm{HPO}_3+2 \mathrm{~N}_2 \mathrm{O}_5 \underset{500 \mathrm{~K}, 9}{\stackrel{\mathrm{Pt}}{\longrightarrow}} 4 \mathrm{Har}^{\mathrm{H}}+\mathrm{P}4 \mathrm{O}{10}$
