Write the concentration equilibrium constant expression for this reaction. cu 2 (aq) 2ag (s) → cu (s) 2ag (aq)
Llana [10]
The redox reaction given is,

                 Cu₍s₎ + 2Ag⁺₍aq₎ ---------> Cu²⁺₍aq₎ + 2Ag₍s₎

The equilibrium constant for this reaction is as follow,

                           Kc = [Cu²⁺][Ag]² / [Cu][Ag⁺]² 
 
                           Kc = [Cu²⁺] / [Ag⁺]²              ∴ {[Cu₍s₎] = 1 & [Ag₍s₎] = 1

So, Above bolded is <span>the concentration equilibrium constant expression for the given reaction.</span>
