Hydrogen (H 2 ) and iodine (I 2 ) react to produce hydroiodic acid (HI).

CH 104: DETERMINATION OF AN EQUILIBRIUM CONSTANT EQUILIBRIUM. Hydrogen (H 2 ) and iodine (I 2 ) react to produce hydroiodic acid (HI). Forward Reaction : H 2(g) + I 2(g) ? 2HI (g) However, as soon as some HI is produced it begins to dissociate back to H 2 and I 2 .
