Question
Ammonia may be oxidized to ni trogen monoxide in the presence of a catalyst according to th e equation as:
4NH3 + 5O2 → 4NO + 6H2O
If 27L of reactants are consumed, what volume of ni trogen monoxide is produced at the same temperature and pressure?
Solution
4NH3 + 5O2 → 4NO + 6H2O
4 vol. 5 vol. 4 vol.
Volume of reactants = 4 vol. of ammonia + 5 vol. of oxygen = 9 vol. .
9 vol. of reactants produces 4 vol. of Nitric oxide
Therefore, 27 vol. of reactants will produce 4 x 27 lit/9 =
12 litres of Nitric oxide.
