Equilibrium Question 690

Question: Suppose the reaction $ PC{l_{5(s)}} $ ⇌ $ PC{l_{3(s)}}+C{l_{2(g)}} $ is in a closed vessel at equilibrium stage. What is the effect on equilibrium concentration of $ C{l_{2(g)}} $ by adding $ PCl_5 $ at constant temperature [MP PMT 1992]

Options:

A) Decreases

B) Increases

C) Unaffected

D) Cannot be described without the value of $ K_{p} $

Show Answer
