At 2000°C, 5.0×10-3 mol CO2 is introduced into a 1.0 L container and the following reaction comes to equilibrium:
2CO2(g) <-> 2CO(g) + O2(g)
Kc = 6.4×10-7
a. Calculate the equilibrium concentrations of CO and O2.
b. What fraction of the CO2 is decomposed at equilibrium? (37% or 6.3%)
Set up an ICE chart, substitute into the Kc expression, and solve for the concns. Post your work if you get stuck.
