9) Industrially, nitric acid (HNO3) is produced by the Oswald process represented by the following - what mass of NH3 is needed to produce 5 tones of HNO3? How much Oxygen is required?
4NH3 + 5O2 = 4NO = 6H20
2NO + O2 = 2NO2
2NO2 + H2O = HNO3 + HNO2
4NH3 + 5O2 => 4NO + 6H20 ---(1)
<br>2NO + O2 => 2NO2 ----(2)
<br>2NO2 + H2O => HNO3 + HNO2 ----(3)
<br>From the reaction is can be seen that 2 moles of NH3 gives 2 moles of NO (1)
<br>2 moles of NO gives 2 moles of NO2 (2)
<br>and 2 moles of NO2 gives 1 mole of HNO3 (3)
<br>THis implies that 2 moles of NH3 gives 1 ...
The question is answered with easy steps and explanations.
