What terms would best describe the above coupled reaction? A. it is non-spontaneous and endothermic (because the overall Go is positive) B. it is spontaneous and exothermic (because the overall Go is positive) C. it is non-spontaneous and exothermic (because the overall Go is positive) D. it is spontaneous and exothermic (because the overall Go is negative) E. it is non-spontaneous and endothermic (because the overall Go is negative)

You have a reaction that takes 8 hours to reach completion at 20 degrees celcius. What is the likely result of changing the temperature to 30 degrees celcius?  a. the reaction should take less times  b. reaction time would be unaffected  c. the reaction should take more time  Which would be the correct answer to this question?

Consider the following free energy diagram for an uncatalyzed and enzyme-catalyzed reaction. Select all the statements that are true. Without enzyme With enzyme A+B Time AB Oa. The reaction is now spontaneous due to the addition of enzyme b. The rate of the enzyme catalyzed reaction is faster than the uncatalyzed reaction O C. The reaction is exergonic O d. The change in free energy for the reaction is greater in the catalyzed reaction, compared to the uncatalyzed reaction e. The enzyme stabilizes the transition state for the reaction Released Energy pes

The enzyme E catalyzes the chemical reaction, X ⇌ Y. Imagine two different cases, a) initial concentration of X is low, and b) initial concentration of X is high. Now, if you start adding X, the initial velocity will increase until it reaches its maximum level. In which case, the initial velocity will increase linearly with an increase in the concentration of X?  why?
