The system will shift towards the reactant's side.
A chemical formula showing the simplest ratio of elements in a compound rather than the total number of atoms in the molecule
[tex]PCl_5[/tex] (g) is removed. As [tex]PCl_5[/tex] (g) is removed/concentration decreases, the equilibrium will shift to oppose the change.
According to principle when the concentration of reactant decreases, the equilibrium shift towards the reactant side.
Hence, equilibrium will shift towards reactants.
