According to Le Chatelier's principle, if you add more hydrogen gas (H2) to the system, the equilibrium will shift to counteract that change by producing more hydrogen iodide (HI). Therefore, the correct response is:
**The amount of hydrogen iodide (HI) increases.**
**The amount of hydrogen iodide (HI) increases.**
