Unformatted text preview: 3 O 2 (g) ' 2 O 3 (g). To shift this reaction to the reactants: a. You could _____________ the pressure. ( increase or decrease) b. You could _____________ the volume. ( increase or decrease) c. You could ______________ oxygen gas. ( add or remove) d. You could _____________ the temperature. ( increase or decrease) 5. Calculate the equilibrium constant K c for this unbalanced reaction: 2 SO 3 (g) ' 2 SO 2 (g) + O 2 (g) Given: [SO 3 ] = 0.0255M, [SO 2 ] = 1.08M, and [O 2 ] = 1.45M at equilibrium. 6. Write the equilibrium expression K c for the reaction between potassium phosphate and calcium nitrate in water. Show the balanced reaction. 7. A 1.000 L flask is initially filled with 1.000 mole of hydrogen gas and 2.000 moles of iodine gas at 448 o C. At this temperature K c is 50.5. Calculate the equilibrium concentrations for all the chemical species in the reaction, which is hydrogen gas and iodine gas produce HI gas....
