Q. Will the dissociation of PCl5 in the reaction PCl5(g)PCl3(g)+Cl2(g);ΔH=+2.22 Kcal be favoured by

AMUAMU 1996

Solution:

: As the reaction is endothermic and accompanied by an increase in volume, according to Le Chateliers principle favourable conditions for dissociation of PCl5 is increase in temperature and decrease in pressure.
