Calculate the pressure of CO(2) gas at 7...

Calculate the pressure of `CO_(2)` gas at `700 K` in the heterogenous equilibrium reaction `CaCO_(3)(s) hArr CaO(s)+CO_(2)(g),` if `DeltaG^(ɵ)` for this reaction is `130.2 kJ mol^(-1)`.

Text Solution

Verified by Experts

For the reaction,
`CaCO_(3)(s) overset(K_(p))(hArr) CaO(s)+CO_(2)(g)`
`K_(p)=P_(CO_(2))`
We know that, `DeltaG^(ɵ)=-RT ln K_(p)`
`:. ln K_(p)=(-DeltaG^(ɵ))/(RT)=-((130.2xx10^(3) J "mol"^(-1))/(8.314 J K^(-1) "mol"^(-1) xx700K))`
or `K_(p)= antilog ((-130.2xx10^(3) J "mol"^(-1))/(8.314 J K^(-1) "mol"^(-1)xx700K))`
`=1.94xx10^(-10) "atm"`
or `P_(CO_(2))=K_(p)=1.94xx10^(-10) "atm"`
