Two systems PCl 5 (g) ⇌ PCl 3 (g) + Cl 2 (g) and SO 2 Cl 2 (g) ⇌ SO 2 (g) + Cl 2 (g) are simultaneously in equilibrium in a vessel at constant volume. If some SO 2 is introduced into the vessel, then

Question

Two systems PCl 5 (g) ⇌ PCl 3 (g) + Cl 2 (g) and SO 2 Cl 2 (g) ⇌ SO 2 (g) + Cl 2 (g) are simultaneously in equilibrium in a vessel at constant volume. If some SO 2 is introduced into the vessel, then at the new equilibrium, the moles of

TestHub · Accepted Answer

Adding SO 2 shifts SO 2 Cl 2 ⇌ SO 2 + Cl 2 to the left, consuming Cl 2 Fall in Cl 2 pulls PCl 5 ⇌ PCl 3 + Cl 2 to the right So more PCl 5 dissociates and the moles of PCl 5 decrease This is option (c).
