Question

LeChatelier's Principle: Qualitative Interpretation Consider the following equilibrium: PCl5 (g)PCl3 (g) + Cl2 (9) Select all of the following statements are true. Increasing the volume of the reaction vessel wll lead to formation of more Cl2 (9) Removing Cl2 (g) from the reaction vessel will lead to the formation of more PCIs(g). a Decreasing the volume of the reaction vessel will cause the equilibrium to produce more products. Increasing the pressure of PCIs (g) will ead to the formation of more PClh (9) Increasing the pressure of PCl3 (g) will decrease the value of Kc for this reaction.

Answer 1

(1) correct: Inceasing the volume of vessel will leads to form more Cl₂ because the volume of product is more than reactant and hence to counter the effect of volume increase , the reaction should shift right hand side to fill more volume.

(2)False : Removing Cl₂ will form more PCl₃

(3)correct:decreasing volume will form more PCl₅

(4)correct: Increasing pressure of PCl₅ will form more PCl₃

(5)False: K_c only depends on temperature and not on concentration
