In a closed container of volume V litre, the following equilibrium has been established at T kelvinH2(g)+I2(s)⇌2HI(g)KC=4If  HI(g) was introduced into another closed container of volume 2V litre at same temperature and the decomposition allowed to reach equilibrium. The value of equilibrium constant is ___?

In V litre container  KC=[HI]2H2I2                                    = 4  In 2V litre container Kc=H2I2[HI]2                                          =0.25 Value of equilibrium constant remain unaltered even though we change the volume at same temperature.since it is decompostition of HI value of equillibrium constant will be reciprocal
