According to Le Chatelier's principle, adding more Cl2(g) to the system will shift the equilibrium to the right in order to consume some of the added Cl2(g). This means that more PCl5(g) will be formed, leading to an increase in its partial pressure while decreasing the partial pressure of PCl3(g). Therefore, the ratio of PCl5(g) to PCl3(g) will increase.

Consider the Following System at Equilibrium at 25°C: PCl3(g)+ Cl2(g) Δ\DeltaΔ

Consider the Following System at Equilibrium at 25°C:
PCl₃(g)+ Cl₂(g) $\Delta$
