Q. Two sample of HI each of 5 gm. were taken seperately into vessels of volume 5 and 10 litres respectively at 27 ° C. The extent of dissociation of HI will be :-
(1) More in 5 litre vessel
(2) More in 10 litre vessel
(3) Equal in both vessel
(4) None of these

The dissociation of a molecule in a reaction depends on temperature, pressure and concentration. It is independent of the volume of the system. Thus, correct option is (C) as the temperature, pressure and concentration are same for both the systems.
