Consider the reaction. PCl 5 (g) - ⇀ ↽ - PCl 3 (g) + Cl 2 (g) K c = 0.0420 The concentrations of the products at equilibrium are [ PCl 3 ] = 0.170 M and [ Cl 2 ] = 0.280 M. What is the concentration of the reactant, PCl 5, at equilibrium?

    The concentration of the reaction PCl5 is 1, 133M

    Explanation:

    The equilibrium constant Kc is the ratio of the products to their reactants, each elevated with its stoichiometric coefficients. In this case:

    Kc = (products) / (reactants)

    Kc = (PCl3) x (Cl2) / (PCl5)

    (PCl5) = (PCl3) x (Cl2) / Kc = 0,170M x 0280 M / 0,0420

    (PCl5) = 1, 133 M
