A.) For the reaction: 2Cl2 (g) + 2H2O(g) <----> 4HCl(g) + O2 (g), Kp = 6.4 x 10-6 at 500 K. If a fixed volume is filled with initial concentrations of these gases at 227 oC such that [Cl2] = 0.5 M, [H2O] = 0.40 M, [HCl] = 0.5 M, and [O2] = 0.015 M, in which direction will the reaction proceed?

b.) 4.00 mol chlotine and 2.00 mol bromine were placed in a 50.0 L container and kept at 293 K until equilibrium was achieved for the reaction,
Br2 (l) + Cl2 (g) <--> 2BrCl (g)

At the point of equilibrium there were 82.63 g of Br2 (l)

Compute the value of Kc for this reaction.
