Problem
A sealed container at constant temperature contains the equilibrium mixture for
3H2(g)+N2(g)⇌2NH3(g).
Immediately after a small quantity of pure N2(g) is injected, the system is allowed to re-establish equilibrium. In the new equilibrium state, the mole fraction of NH3 is larger than it was before the injection. In one sentence, explain why the concentration of NH3 increased.
