Using the Gibbs energy change, DeltaG^(@) =+63.3 kJ,for the following reaction, Ag_(2)CO_(3)(s) ""2Ag^(+)(aq)+CO_(3)^(2-)(aq)theK_(sp)" of "Ag_(2)CO_(3)(s) in water at 25^(@)C is (R=8.314 J K^(-1)mol^(-1))

Answer»

`2.9 xx 10^(-3)`
`7.9 xx 10^(-2)`
`3.2 xx 10^(-26)`
`8.0 xx 10^(-12)`

Solution :`DeltaG^(@)=-2.303" RT log Ksp"`
`63300=-2.303xx8.314xx298 log K_(sp)`
`K_(sp)=8xx10^(-12)`
