Our topic is chemical equilibrium. Thank you!

1. What happens to the equilibrium 2NO(g) + O2(g) = 2NO2(g) if ...(indicate the equilibrium shift) a. O2 were added to the system, and b. NO were removed? 2. For the reaction As Oc(s) + 6C) = Asa(g) + 6CO(g), predict the direction of the shift of the equilibrium position in response to the following: a. addition of CO; b. addition or removal of As406 C. removal of As4 3. How would you change the volume of each of the following reactions to increase the yield of the products? a. CaCO3(s) = CaO(s) + CO2(g) b. Sis) + 3F2(9) SF6(a) C. Cl2(g) + 12(g) = 2ICLE) 4. Consider the equilibrium, N2O4(g) = 2NO2(g) AHran = 58.0 kJ. In which direction will the equilibrium shift when the system is: a. heated? b. soaked in an ice bath? C. made to occur on the surface of a Pt metal catalyst
