Question

Using the Gibbs energy change, Δ G ° = + 63.3 kJ , for the following reaction, A g 2 C O 3 → 2 A g + ( a q ) + C O 3 2 - ( a q ) the K s p of A g 2 C O 3 ( s ) in water at 25 o C is ( R = 8.314 J K - 1 m o l - 1 ) Given: 10 0.91 ≅ 8, 7.9 × 1 0 - 2, 8.0 × 1 0 - 12, 2.9 × 1 0 - 3, 3.2 × 1 0 - 26

ΔG o = − 2.303 RT log K sp 63.3 × 1000 = - 2.303 × 8.314 × 298 log ⁡ K s p log ⁡ K s p = - 11.09 K s p = 1 0 - 11.09 = 8 × 1 0 - 12
