SO_(2)CI_(2) harr SO_(2) +Cl_(2) (gascous): PCI_(5) harr PCI_(3) + Cl_(2) (gaseous) of some SO_(2) is removed from the above set of equillibria occuring in same closed container

Answer»

Degree of dissociation of `SO_(2)Cl_(2)` decreases
Degree of dissociation of `PCl_(5)` decreases
Degree of dissociation of `SO_(2)Cl_(2)` increases
Concentration of `PCI_(3)` decreases

Solution :When `SO_(2)` in removed equation 1 SHIFTS forward
`:. Cl_(2)` is produced, HELVE equation 2 shifts backward i.e., `[PCl_(5)]` in CREASES `[PCI_(3)]` decreases
