In the preparation of HNO3, we get NO gas by catalytic oxidation of ammonia. The moles of NO produced by the oxidation of two moles of NH3 will be ______.

Two moles of NH3 will produce 2 moles of NO on catalytic oxidation of ammonia in preparation of nitric acid.


2NH3 + O2 2NO + 3H2O


(In this reaction Pt acts as catalyst)


Hence the correct option is (i)
