Large0Scale manufactring of nitric acid by Ostwald process utilizes the reaction

A

`2NaNO_(3)+H_(2)SO_(4)rarrNa_(2)SO_(4)+2HNO_(3)`

B

`4NH_(3)+5O_(2)rarr4NO+6H_(2)O`

C

`NO_(2)^(+)+NO_(3)^(-)+H_(2)Orarr2HNO_(3)`

D

`2NO+O_(2)+H_(2)OrarrHNO_(3)+HNO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
The restricted oxidation of `NH_(3)` can done with air, when air, when the mixure is passed oveer heated platinum gauze at `700^(@)C` to `800^(@)C`.
`4NH_(3)+50_(2)rarr4NO+6H_(2)O+underset(Calo ries)21600`
`NO+O_(2)rarr2NO_(2)`
`3NO_(2)+H_(2)Orarr2HNO_(3)+NO`
This is the Ostwald's process used for manufactring of `HNO_(3)`
