Calculate K for the reaction. b) A 1.00 L flask is charged with 0.00513 moles of Al2Cl6 at 454 K and allowed to establish equilibrium (in other words, is held at T until equilibrium is established). Estimate, to three significant figures, the molar concentrations, mol/L (M), of both species after the system has attained equilibrium.
