at a particular temperature, k equals 2.0 x 10 to the -6 power for the reaction 2CO2 <-> 2CO + O2 if 2.0 mol CO2 is initially placed into a 5.0 L vessel, calculate the equilibrium concentration of all species

I assume this is Kc and knot Kp.
Initial (CO2) = 2.00mol/5.0L = 0.40
..........2CO2 ==> 2CO + O2
I.........0.40......0.....0
C.........-2x......2x......x
E........0.4-2x...2x......x

Substitute the E line of the ICE chart into the Kc expression and solve for x, 2x, and 04-2x.
Post your work if you get stuck.
