Which infornation does the pre-exponentail factor contain?

6. Identify the reagents that would allow accomplishing each of the following transformations. More than one reagent and one step may be required. Pay close attention to stereochemistry. As a good practice, determine if the reaction goes through SN1 or SN2 mechanism.

2. The specific gravities (S.G.) of a number of radio-active components have been determined. The masses of the components have been found accurately, by weighing them, but their geometry is complex and the volumes have been found by using the water- displacement method. 18-7 18-3 18-4 18.9 18-8 18.6 19-2 18.9 19-8 18-8 17:0 19-5 19.3 (a) Give details of the likely concerns associated with this process. (b) Perform a simple Q-test of the data to determine any outliers. (c) Using those data that you are confident are reliable, calculate the mean S.G. to 4 s.f. (d) Using those data that you are confident are reliable, calculate the standard deviation associated with the S.Gs to 3 s.f.

Using the values below indicate the pKa at each of the boldfaced hydrogens. Some values may be used multiple times some may not be used at all pKa's: -6, -2, 0, 3-5, 5-7, 9-11, ~16.5, 16-18, 19-21, 25, 30, 32, 35-38, 41, 44, 50.

1) What is the subject of each of the figures above ? 2) What is the main message of figure? 3) Give a brief but complete description of the three sections of the chemical mechanism along with a statement on the significance of the reaction.

What chemical process is known as saponification (soap forming reaction)? transmit mechanism.

When the paramagnetic species are very close together, or are separated by a species that can transmit magnetic interactions, this will give rise to а. magnetically dilute species. b. ferromagnetism or antiferromagnetism. С. only antiferromagnetism. d. only ferromagnetism

A research group discovers a new version of the rainbowase enzyme, which they call rainbowase*, that catalyzes the chemical reaction: RAIN rainbows The researchers began to characterize the enzyme. a) In the 1st experiment, with [E] at 4 nM, they find that the Vmax is 1.6 uM s-1. Based on this experiment, what is the kcat for rainbowase*? (include units and show work). b) In another experiment, the [E] at 1 nM and [RAIN] at 30 µM, the researchers find that V. = 300 nM s-1. What is the measure KM for rainbowase* for its substrate RAIN? (include units and show work).
