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). Determine the total pressure in the 50.0 L container at equilibrium.
