for the given reaction is 7.7
![K_{sp}(Ag_{2}CO_{3})=[Ag^{+}]^{2}[CO_{3}^{2-}]](/tpl/images/0413/8617/b8832.png)
![K_{sp}(Ag_{2}CrO_{4})=[Ag^{+}]^{2}[CrO_{4}^{2-}]](/tpl/images/0413/8617/31f53.png)
represents solubility product![K_{c}=\frac{[CO_{3}^{2-}]}{[CrO_{4}^{2-}]}](/tpl/images/0413/8617/fea9e.png)
(concentration of pure solids remain constant during reaction. Hence their concentration is taken as 1 to exclude them from equilibrium constant expression)![K_{c}=\frac{[Ag^{+}]^{2}[CO_{3}^{2-}]}{[Ag^{+}]^{2}[CrO_{4}^{2-}]}](/tpl/images/0413/8617/3fc1b.png)
