For the reaction:

PCl₅(g) $⇌$ PCl₃(g) + Cl₂(g)

The forward reaction is favoured by

Answer:

C, D

Solution:

Forward reaction increases gaseous moles (1 → 2).At constant pressure, adding inert gas increases volume, so equilibrium shifts towards more

moles → forward reaction favoured.

The reaction is endothermic, so increase in temperature favours the forward direction.
