In the ostwahTs process, nitric acid is prepared by the catalytic oxidation of:

A)  \[{{N}_{2}}\]                                      

B)  \[N{{H}_{3}}\]

C)  \[{{N}_{2}}{{O}_{5}}\]                                 

D)  \[N{{O}_{2}}\]

Correct Answer: B

Solution :

Reaction involve in Ostwald sprocess: \[4N{{H}_{3}}(g)\,+5{{O}_{2}}(g)\] \[4NO(g)\,+6{{H}_{2}}O(g)\] \[NO+1/2{{O}_{2}}\xrightarrow{\,}N{{O}_{2}};\] \[3N{{O}_{2}}\,+{{H}_{2}}O\xrightarrow{\,}\,2HN{{O}_{3}}+NO\].
