The equilibrium constant expression for FeCl3 +3KSCN → Fe(SCN)3 + 3KCl is


(Fe(SCN)3) (KCl)^3 / (FeCl3)(KSCN)^3



Explanation

Equilibrium constant expression is given by concentration of the products raised to their coefficient divided by concentration of reactants raised to their coefficient. KCl and KSCN is raised to three since they have a coefficient of three from the equation.
