Expert Answer:

Rate of dissociation is high in the case of silver nitrate as it is an ionic molecule where as Sodium argentocyanide or potassium argentocyanide are Coordination complex molecules. During the dissociation of Sodium argentocyanide (or) potassium argentocyanide, the rate gets slow down as silver is present inside the complex whereas in case of silver nitrate, silver ions are released at a faster rate.
