A.) Some PCl5 is placed in a flask and heated to 691 K. When equilibrium is reached, the flask is found to contain PCl5 (1.47×10-4 M), PCl3 (3.13×10-2 M), and Cl2 (1.42×10-2 M). What is the value of the equilibrium constant for the following at reaction at 691 K? PCl5(g) PCl3(g) + Cl2(g) K = B.) Consider the following reaction where Kc = 77.5 at 600 K. CO(g)+Cl2(g) COCl2(g) A reaction mixture was found to contain 5.12×10-2 moles of CO(g), 4.10×10-2 moles of Cl2(g) and 0.125 moles of COCl2(g), in a 1.00 liter container.Is the reaction at
