Question 1: Equilibrium (11 points) a. Use the CO 2 phase diagram to answer the following questions. (4 points) i. Circle the triple point on the CO 2 phase diagram. Describe what is happening at the triple point. (2 points) The triple point is around 5atm and -55 degrees. Solid, liquid, and gas are living together. ii. How does the triple point represent a dynamic equilibrium? (2 points) The substance is losing reactants/products but the substance move’s between the chemicals at an equal rate. b. Use the reaction 2CO( g ) + O 2 ( g ) 2CO 2 ( g ) for the following questions. (7 points) i. Write the equilibrium constant for the reaction. (1 point) CO2^2/(2CO)(O2) ii. What does Le Châtelier's principle predict would happen to the equilibrium conditions if CO 2 were added to the system? (1 point) According to the principle if CO2 were added to a system at equilibrium then all the concentrations would change in the equilibrium and the system would no longer be at equilibrium.

iii. What would happen to the equilibrium if the pressure were increased? (1 point) The equilibrium would shift toward the side of the reactant iv. A gas mixture contains 4.8 10 –4 M CO and 3.5 10 –2 M O 2 , and K eq = 3.58 10 –4 . What would the equilibrium concentration of CO 2 be at these conditions? (2 points) The equilibrium concentration here would be 8.495 time 10^-7 v. If at another temperature the K eq = 8.28 10 10 , would the reaction favor product formation or reactants? Explain your answer. (2 points) Question 2: Acids and Bases (10 points) a. Arrhenius acid-base reaction (3 points) i. Complete the following acid-base reaction. What does it mean that HI is a strong acid and CsOH is a strong base? (2 points) HI + CsOH HI is a strong acid because it has a weak bond form and can easily lose a hydrogen atom. CsOH is a strong base because it completely dissociates in any liquid

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
