The following sequence of reaction occurs in commical production of aqueous nitric acid.
`NH_(3)(g)+O_(2)(g) rarr NO(g)+H_(2)O(l)`
`NO(g)+O_(2)(g)rarr NO_(2)(g)`
`NO_(2)(g)+H_(2)O(l) rarr HNO_(3)(aq)+NO(g)`
In an industry , 378 kg of `HNO_(3)` was required to be produced. If % yield of all reactions is 100% , then mass (kg) of `NH_(3)` , required is :[NO produced is reactionp-(iii) re-used in reaction-(ii)]
