The equilibrium constant, K, for the following reaction is 10.5 at 350 K. 2CH2Cl2(g) CH4(g) + CCl4(g)

An equilibrium mixture of the three gases in a 1.00 L flask at 350 K contains 5.19×10-2 M CH2Cl2, 0.168 M CH4 and 0.168 M CCl4. What will be the concentrations of the three gases once equilibrium has been reestablished, if 4.07×10-2 mol of CH2Cl2(g) is added to the flask?
