1 mole each of `H_2(g)and I_2(g)` are introduced in a 1L evacuated vessel at 523 K and equilibrium `H_2(g)+I_2(g)hArr2HI(g)` is established. The concentration of HI(g) at equilibrium:

A

changes on changing pressure.

B

change on changing temperature.

C

is same even if only 2 mol of HI(g) were introduced in the vessel in the begining.

D

is same even when a platinum gauze is introduced to catalyse the reaction.
