In the reaction PCl₅ ⇔ PCl₃ + Cl₂ at 500 K, the equilibrium concentrations of each species are
[PCl₅] = 0.008 M, [PCl₃] = 0.02 M, and [Cl₂] = 0.02 M. The equilibrium constant value is 0.5.

Question

Quizplus · Accepted Answer

The equilibrium constant value (Kc) is calculated by dividing the product of the concentrations of the products by the product of the concentrations of the reactants, each raised to their stoichiometric coefficients. Kc = ([PCl₃][Cl₂])/[PCl₅] = (0.02 x 0.02)/(0.008) = 0.05 Since the given equilibrium constant value is 0.5 and the calculated value of Kc is 0.05, the answer is false.
