Using the Gibbs energy change, 
G° = +63.3 kJ , for the following reaction, Ag 2 CO 3 
2Ag + (aq) + 
(aq) the K sp of Ag 2 CO 3 (s) in water at 25°C is (R = 8.314 JK -1 mol -1 ) {Given: 10 0.91 
8}
Text Solution
Verified by ExpertsThe correct answer is:
B
8.0 x 10 -12
G° = -2.303 RT log K sp
63.3 x 1000 - -2.303 x 8.314 x 2981ogK sp
log K sp = -11.09
K sp =10 -11.09 =8x10 -12
