The reaction for producing ammonia is described by the following chemical reaction equation:
N2 + 3H2 = 2NH3;
The nitrogen molecule has two nitrogen atoms, and the ammonia molecule has one nitrogen atom. Therefore, from one mole of nitrogen, two moles of ammonia can be obtained.
A hydrogen molecule has two hydrogen atoms, and an ammonia molecule has three hydrogen atoms. Therefore, 2/3 mol of ammonia can be obtained from one mole of hydrogen.
Thus, one mole of nitrogen will react with three moles of hydrogen.
Let’s determine the amount of substance in 14 grams of nitrogen.
Its molar mass is:
M N2 = 14 + 14 = 28 grams / mol;
The amount of the substance will be:
N N2 = 14/28 = 0.5 mol;
With this amount of nitrogen, 0.5 x 3 = 1.5 mol of hydrogen will react.
One mole of ideal gas under normal conditions takes a volume of 22.4 liters.
Its volume will be
V H2 = 1.5 x 22.4 = 33.6 liters;
