According to Le Chatelier's principle, on applying any external force to desturb equilibrium, the reaction moves in that direction in which effect of exteranal force is minimised as far as possible. A container whose volume is V contains an equilibrium mixture that contains 2 moles each of `PCl_(5)`, `PCl_(3)` and `Cl_(2)`n (all gases). The pressure is 3atm and temperature is T. A certain amount of `Cl_(2)(g)` is now introduced keeping the pressure and temperature constant untill the equilbrium volume changes to 2 V.
`PCl_(5)(g)hArrPCl_(3)(g)+Cl_(2)(g)`. The moles `Cl_(2)` that was added is :

A

2

B

`(10)/(7)`

C

`(8)/(3)`

D

`(20)/(3)`

According to Le Chatelier's principle, on applying any external force to desturb equilibrium, the reaction moves in that direction in which effect of exteranal force is minimised as far as possible. A container whose volume is V contains an equilibrium mixture that contains 2 moles each of PCl_(5) , PCl_(3) and Cl_(2) n (all gases). The pressure is 3atm and temperature is T. A certain amount of Cl_(2)(g) is now introduced keeping the pressure and temperature constant untill the equilbrium volume changes to 2 V. PCl_(5)(g)hArrPCl_(3)(g)+Cl_(2)(g) . The equilibrium constant K of the reaction :

For the reaction, PCl_(5)(g)to PCl_(3)(g)+Cl_(2)(g)

A container of volume V L contains an equilibrium mixture that consists of 2 mol each of gaseous PCl_(5), Pcl_(3) and Cl_(2) at 3 atm T K . Some Cl_(2) is added unitl the volume is double keeping P and T constant. Calculate moles of Cl_(2) added and K_(p) for PCl_(5) rarr PCl_(3)+Cl_(2)
