At 473 K,`K_(c)` for the reaction
`PCl_(5(g))rArrPCl_(3(g))Cl_(2(g))` is `8.3xx10^(-3)`. What will be the value of `K_(c)` for the formation of `PCl_(5)` at the same temperature ?

A

`8.3xx10^(3)`

B

`120.48`

C

`8.3xx10^(-3)`

D

240.8

Text Solution

Verified by Experts

The correct Answer is:
B
`PCl_(5(g))hArrPCl_(3(g))+Cl_(2(g)),K_(c)=8.3xx10^(-3)`
`"For "PCl_(3(g))+Cl_(2(g))hArrPCl_(5(g)),K_(c)=(1)/(8.3xx10^(-3))`
`K_(c)=(1)/(8.3)xx10^(3)=120.48`
