Using the Gibbs energy change G^(@)=+63....

Using the Gibbs energy change `G^(@)=+63.3kJ` for the given reaction: `Ag_2CO_3(s)hArr2Ag^(+)(aq)+CO_3^(2-)`(aq), the `K_(sp)` of `Ag_2CO_3`(s) in water at `25^(@)C` is `(R=8.314J*K^(-1).mol^(-1))`

A

`3.2xx10^(-26)`

B

`2.9xx10^(-3)`

C

`8.12xx10^(-12)`

D

`7.9xx10^(-12)`

Text Solution

Verified by Experts

`/_\G^0=-RTInK_(sp)=*2.303RT log K_(sp)`
`63.3xx10^3=-2.303xx8.314xx298log K_(sp)`
`K_(sp)=8.12xx10^(-12)`
