What will be the concentrations of the three gases once

Question

The equilibrium constant, K, for the following reaction is 1.29×10^-2 at 600 K.

• COCl₂(g) <-----> CO(g) + Cl₂(g)

An equilibrium mixture of the three gases in a 1.00 L flask at 600 K contains 0.170 M COCl₂, 4.69×10^-2 M CO and 4.69×10^-2 M Cl₂. What will be the concentrations of the three gases once equilibrium has been reestablished, if 2.50×10^-2 mol of CO(g) is added to the flask? 

[COCl₂]=________ M

[CO]= _________M

[Cl₂]=_________ M
