Chemistry

The equilibrium constant, K, for the following reaction is1.20×10-2 at 500 K. PCl5(g) PCl3(g) + Cl2(g) An equilibrium mixtureof the three gases in a 1.00 L flask at 500 K contains 0.200 MPCl5, 4.90×10-2 M PCl3 and 4.90×10-2 M Cl2. What will be theconcentrations of the three gases once equilibrium has beenreestablished, if 3.12×10-2 mol of Cl2(g) is added to theflask?

[PCl5] =

[PCl3] =

[Cl2] =
