Question

Gaseous hydrogen iodide is placed in a closed container at 425 ∘C ∘ C , where it partially decomposes to hydrogen and iodine: 2HI(g)←→H2(g)+I2(g) 2 H I ( g ) ← → H 2 ( g ) + I 2 ( g ) . At equilibrium it is found that [HI]= [ H I ] = 3.51×10−3 M M , [H2]= [ H 2 ] = 4.76×10−4 M M , and [I2]= [ I 2 ]
