Use the reaction 2CO(g) + O2(g) 2CO2(g) for the following questions.
i. Write the equilibrium constant for the reaction.
ii. What does Le Châtelier's principle predict would happen to the equilibrium conditions if CO2 were added to the system?
iii. What would happen to the equilibrium if the pressure were increased?
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.
