Answer:
K = [Cu2^+] / [Ag^+]^2
Explanation:
The equilibrium expression written for a system in equilibrium must take into account the balanced equation for the reaction and the phases (solid, liquid, gas, or dissolved) of each species involved in the reaction.
aA + bB ⇆ cC + dD
Kc = [C]^c + [D]^d / [A]^a + [B]^b
"[ ]" - concentration of the species (moles per liter or molarity)
"a, b, c, d" - coefficients used to balance the equation
"c in Kc" - indicates that the value of K is determined using the concentrations of each species
There are two cases when a species is not shown in the equilibrium expression: when it is a solid and when it is a pure liquid or solvent.
