At a certain temperature, the reaction `PCl_(5)(g)hArrPCl_(3)(g) + Cl_(2)(g)` has an equilibrium constant `K_(c) = 5.8 ×x 10^(-2)`. Calculate the equilibrium concentrations of `PCl_(5), PCl_(3)` and `Cl_(2)` if only `PCl_(5)` is present initially, at a concentration of 0.160 M.

Explanation

`[PCl_(3)] = [Cl_(2)] = 0.071 M, [PCl_(5)] = 0.089`
