Using the Gibbs energy change, `Delta G^(@)=+ 63.3 kJ`, for the following reaction,
`Ag_(2)CO_(3)hArr2Ag^(+)(aq)+CO_(3)^(2-)`
the `K_(sp)` of `Ag_(2)CO_(3)(s)` in water at `25^(@)C` is
`(R=8.314 JK^(-1)mol^(-1))`

A

`2.9 xx 10^(-3)`

B

`7.9 xx 10^(-2)`

C

`3.2 xx 10^(-26)`

D

`8.0 xx 10^(-12)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Delta G^(@) = -2.303RT log Ksp`
63300 `= -2.303 xx 8.314 xx 298 log K_(sp)`
`K_(sp) = 8 xx 10^(-12)`
