| Effect
of adding H2 to an equilibrium mixture of N2, H2,
and NH3. |
|
| Caption: |
|
| When H2
is added to an equilibrium mixture of N2, H2, and NH3,
a portion of the H2 reacts with N2 to form NH3,
thereby establishing a new equilibrium position that has the same equilibrium
constant. The results are shown in
accordance with Le Châtelier’s principle. |
