3) What was the experimentally determined K eq average? What is the theoretical K eq for this reaction? How does your experimental value compare to the theoretical value and what are some factors that may have played a role in causing differing values? Trial 1- K eq = 11.3 Trial 2- K eq = 473.3 Trial 3- K eq = 206.04 Trial 4- K eq = 169.8 Trial 5- K eq = 228.5 Average K eq = 217.79 Theoretical K eq = 138.11 @ 25 C The experimental value we obtained is significantly more than the theoretical literature value. The reasoning for differing values can be due to measurement errors when pipetting. Since we were working with such small measurements it was very difficult to make sure only 1mL made it

Explain your reasoning in terms of what is means to have a relatively small K eq versus a relatively large K eq ? All of our K eq values appear to be very large. When K is very large the reaction is starting out with almost all products and very little reactants. The reaction must shift left to make more reactants and reach equilibrium. When K eq is very small the reaction contains almost all reactants and very little products. The reaction moves right to create more products to reach equilibrium....

    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.
