Two moles of `PCl_(5)` were heated at `327^(@)C` in a closed two litre vessel and when equilibrium was reached, `PCl_(5)` was found to be 40% dissociated into `PCl_(3)` and `Cl_(2)`
The equilibrium constant `K_(rho)` for the above reaction is (approx)
A. 13.14 `atm^(-1)`
B. 13.14 atm
C. 6.52 atm
D. 6.52 `atm^(-1)`
