Question
The system PCl5(g) ⇋ PCl3(g) + Cl2(g) attains equilibrium. If the equilibrium cocentrateion of PCl3(g) is doubled, the concentration of Cl2(g) would become
Options
A.1/4 its original value
B.1/2 its original value
C.Twice its original value
D.Unpredictable
Solution
PCl5 ⇋ PCl3 + Cl2
If the concentration of PCl3 is doubled, it only predicts, that reaction will proceed back ward. (Le-Chatlier′s principle). So the concentration of Cl2 is unpredictable.
