At 473K, equilibrium constant, K(c) for ...

At 473K, equilibrium constant, `K_(c)` for decomposition of phosphorus pentachloride, `PCl_(5)` is `8.3xx10^(-3)`. If decomposition is depicted as :
`PCl_(5(g))hArrPCl_(3(g))+Cl_(2(g)),Delta_(r)H^(@)=124.0" kJ mol"^(-1)`
what would be the effect on reaction if the temperature is increased ?

Text Solution

Verified by Experts

` K. = (1)/(K_C) = (1)/(8.3 xx10 ^(-3)) = 120 .48`
