Answer:

One way is to use the Ostwald process used in industry of nitric acid manufacturing.

Explanation:

First, you would need to oxidize ammonia (#NH_3#). This process is exothermic and is also reversible. This can be modeled by the following equation

#4NH_3+5O_2⇌4NO+6H_2O#

This gives you nitric oxide gas (#NO#), which comes out very hot, so it would be a good idea to cool it down, to about #150# degrees celsius. After further cooling, it gets oxidized to nitrogen dioxide (#NO_2#).

#2NO+O_2⇌2NO_2#

After that, water is poured over the nitrogen dioxide gas and nitric acid is obtained.

#3NO_2+H_2O->2HNO_3+NO#, where nitric acid is #HNO_3#.
