Question
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 ______.
Options
two
three
four
six
Solution
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.
Explanation:
Two moles of NH3 will produce 2 moles of NO on catalytic oxidation of ammonia in preparation of nitric acid
\[\ce{4NH3 + 5O2 ->[Δ][Pt(Rh gauge catalyst)] 4NO(g) + 6H2O(l)}\]
Hence, 2 moles of ammonia will produce 2 moles of No.
