The reaction you provided is:
\[ H_2 + I_2 \rightleftharpoons 2HI \]
According to Le Chatelier's principle, if a system at equilibrium is disturbed by a change in concentration, pressure, or temperature, the equilibrium will shift to counteract that change.
In this case, if more hydrogen gas (Hâ‚‚) is added to the system, the equilibrium will shift to the right to consume the added hydrogen and produce more hydrogen iodide (HI).
Therefore, the correct answer is:
**C. The amount of hydrogen iodide (HI) increases.**
