Question

Full question: The system PCl5(g)PCl3(g)+Cl2(g) attains equilibrium. If the equilibrium concentration of PCl3(g) is doubled, the concentration of Cl2(g) would become

Answer 1

Answer:

1/2 times.

Explanation:

Kc = [PCl3] [Cl2]. -(I)

[PCl5]

Let the new concentration of Cl2 be [Cl2]'

Kc for new equilibrium = 2[PCl3] [Cl2]'. -(II)

[PCl5]

Value of Kc does not changes on changing the equilibrium concentration.

So from (I) and (II)

[PCl3] [Cl2] = 2[PCl3] [Cl2]'

[PCl5] [PCl5]

=> [Cl2]/2 = [Cl2]'
