At 473K, equilibrium constant `K_(c)` for decomposition of `PCl_(5)` is `8.3x10^(-3)`. If decomposition is depicted as, `PCl_(5)(g)hArr PCl_(3)(g)+Cl_(2)(g),`
`DeltaH_(r)^(0)=124.0kJ*mol^(-1)`
What is the value of `K_(c)` for the reverse reaction at the same temperature?

Text Solution

Verified by Experts

For the reverse reaction, `K_(c)=(1)/(8.3xx10^(-3))=120.48`.
