Keq from Equilibrium Composition, Variously Expressed. At some temperature, an equilibrium mixture, in a 1.00-L container, involving the chemical system PCI5(g) = PCI3(g) + Cl2(g) is found to contain 5.74×1020 molecules of PCI5, 0.00921 mol of PCI3, and 0.228 g of Cl2. Calculate the equilibrium constant (Keg expressed in terms of the molar concentrations) at this temperature. (No units required.)
