Title:
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.
