The equilibrium constant expression is always written as the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. In this case, the stoichiometric coefficients are 2 for BrCl and 1 for Br and Cl, respectively. Thus, the correct expression is K_c = [Br₂][Cl₂]³/[BrCl₃]². Option C is the only one that matches this expression.
