Give expression of equilibrium constant of following reactions.
(i)`2Ag_((s)) + Cu_((aq))^(2+) hArr Cu_((s)) + 2Ag_((g))^(+)`
(ii)`O_(2(g)) + 4HCl_((g)) hArr 2H_2O_((g)) + 2Cl_(2(g))`

Explanation

(i)`K_c=[Ag^+]^2/((Cu^(2+)))`
(ii)`K_c=([H_2O]^2[Cl_2]^2)/([O_2][HCl]^4)` and `K_p=((p_(H_2O))^2(p_(Cl_2))^2)/((p_(O_2))(p_(HCl))^4)`
