Given the equilibrium system PCL5(g) <----->PCl3(g) + Cl2(g)
K = 12.5 at 60 degrees celsius. A 1.0 L reaction vessel is analyzed and found to contain 3.2 mol Cl2(g), 1.5 mol PCl3(g) and 2.0 mol PCl5(g). Show that the reaction mixture has not yet reached equilibrium.
Set up the expression for Keq.
Then calculate the reaction quotient and compare with Keq. Post your work if you get stuck.
