Using the Gibbs change, ∆ G o = + 63.3 k J , for the following reaction, A g 2 C O 3 g ⇌ 2 A g + a q + C O 3…

Using the Gibbs change, ∆Go=+63.3 kJ, for the following reaction, Ag2CO3g ⇌2Ag+aq+CO32-aq the Ksp of Ag2CO3s in water at 25oC is R=8.314 JK-1mol-1
  1. 3.2×10-26
  2. 8.0×10-12
  3. 2.9×10-3
  4. 7.9×10-2

Solution

∆Go=-2.303 RTlog⁡Ksp

63.3×103=-2.303×8.31×298log⁡Ksp

-11.09=log⁡Ksp

8×10-12=Ksp
