Use the reaction 2CO(g) + O2(g) 2CO2(g) for the following questions iv. a gas mixture contains 4.8 10–4 M CO and 3.5 10–2 M O2, and Keq = 3.58 10–4. What would the equilibrium concentration of CO2 be at these conditions?

v. If at another temperature the Keq = 8.28 1010, would the reaction favor product formation or reactants? Explain your answer.
