At what [Br-]/√[CO3^2-] does the following cell have its reaction at equilibrium? Ag(s) | Ag2CO3(s) | Na2CO3(aq) || KBr(aq) | AgBr(s) | Ag(s) Ksp = 8×10^12 for Ag2CO3 and Ksp = 4×10^12 for AgBr

Question

At what [Br-]/√[CO3^2-] does the following cell have its reaction at equilibrium?
Ag(s) | Ag2CO3(s) | Na2CO3(aq) || KBr(aq) | AgBr(s) | Ag(s)
Ksp = 8×10^12 for Ag2CO3 and Ksp = 4×10^12 for AgBr
