The industrial preparation of nitric acid by Ostwald's process involves ?

Options

A. Reduction of `NH_(3)`
B. Oxidation of `NH_(3)`
C. Hydronegation of `NH_(3)`
D. Hydrolysis of `NH_(3)`

Answer

B

Explanation

The reactions invovled in ostwald's process for preparation nitric acid are as follows.
`4NH_(3)+5O_(2) to 4NO+6H_(2)O`
`2NO+O_(2) to 2NO_(2)`
`2NO_(2)+H_(2)O+O to 2HNO_(3)`
`therefore`Nitric acid is produced by oxidation of `NH_(3)` in this process.
