Calculate the volume of oxygen that reacts with 3 liters of ammonia. In this case, ammonia is oxidized to nitric oxide (II).
The reaction of non-catalytic oxidation of ammonia with oxygen is described by the following chemical reaction equation:
4NH3 + 3O2 = 2N2 + 6H20;
Let’s calculate the chemical amount of a substance in 3 liters of ammonia.
To do this, we divide its volume by the volume of 1 mole of gas (which is 22.4 liters).
N NH3 = 3 / 22.4 = 0.134 mol;
To oxidize such an amount of a substance, it is necessary to take (in accordance with the coefficients of the chemical equation) 0.134 x 3/4 = 0.1 mol of oxygen.
Determine the volume of gaseous oxygen.
To do this, multiply its amount by the volume of 1 mole of gas (equal to 22.4 liters).
V O2 = 0.1 x 22.4 = 2.24 liters;
