6. A. (10 points) An unknown gas, XY3 0.331 moles, is placed into a 3.00L flask undergoes the reaction (all gas phase): XY3 = x + 3 Y If the equilibrium concentration of the starting material is 2.45x10² M calculate the value of K as well as the equilibrium concentrations of all the other species. 6 B. Briefly answer the changes to the equilibrium system described above: (All NPC 3pts each) i) (3 pts) The pressure of Y is lowered and the temperature is constant. Choose one: Pressure of XY3 is lowered by a factor of 3 Pressure of X is increased 3 times Pressure of XY3 is increased 3 times Pressure of X is lowered by a factor of 3 ii) (3pts) What happens to the amount of product if the volume of the container is increased? iii) (3pts) If the reaction is endothermic, what happens if the product is not removed from the reaction container? iv) (3pts) What happens when Helium is added to the equilibrium mixture?
