The equilibrium:
`P_(4)(g)+6Cl_(2)(g) hArr 4PCl_(3)(g)`
is attained by mixing equal moles of `P_(4)` and `Cl_(2)` in an evacuated vessel. Then at equilibrium:

A

`[Cl_(2)] gt [PCl_(3)]`

B

`[Cl_(2)] gt [P_(4)]`

C

`[P_(4)] gt [Cl_(2)]`

D

`[PCl_(3)]lt[P_(4)] `

Text Solution

Verified by Experts

The correct Answer is:
C
`{: (,P_(4)(s),+,6 Cl_(2)(g),hArr,4 PCl_(3) (g)),("Intial",1 " mole",,1 " mole",,),("At eqm.",1-x,,1-6x,,4x):}`
`" As" (1-x) gt(1-6 x), "hence " [P_(4)] gt [Cl_(2)]`
