Please consider the reaction of 0.22M 2-iodopropane with tetramethylammonium fluoride (TMAF) in DMSO to give propylene. The reaction rate in the presence of 0.1M TMAF is 0.002 M/s, but it is 0.0058 M/s in the presence of 1.2M TMAF.
a. Given the data above, what is kE2 / kE1 , the ratio of rate constants for the E2 and E1 mechanisms?
b. When the ln( kE2 / kE1 ) is plotted vs. 1/T the resulting linear graph has the slope of - 4.8 and intercept of 6.1What is the difference in activation energies of the two mechanisms? For which mechanism are the reactive collisions more efficient?
a graduated cylinder reads 4 ml of water.then a shell is dropped into it and the water level rises to 12 ml.what is the volume of the shell?
For each of the following equilibria, use Le Chatelier's principle to predict the direction of reaction when the volume is increased.
how you will prepare 3-methly-1-butanol from a grignard reagent and any needed aldehyde or ketone.
15 g of steam at 373 K is added to 250 g of H2O (liquid) at 298K at onstant pressure of 1 bar. Is the final state of the system steam or liquid water? Calculate changes in entropy for the process.
What is the pH of a solution that is prepared by dissolving 9.81 grams of acetic acid (60.05 g/mol) and 8.68 grams of sodium acetate (82.03 g/mol) in water and diluting to 800 mL.
The compound malonate is an analog of succinate and is a strong inhibitor of succinate dehydrogenase. The active site of the enzyme will bind to either molecule, however malonate will not undergo any reaction and gets stuck on the enzyme.
Unfortunately, a mixup in the laboratory prevented an immediate analysis, and it was not until 17.0 days later that a measurement on the blood was made.
If CO2 is not removed by boiling after the addition of HCL, how will this affect the determination of moles of base per gram of antacid tablet?
A solution of phosphoric acid was made by dissolving 10 g of H3PO4 in 100 ml of water. The resulting volume was 104 mL. Calculate the density, mole fraction, molarity, and molality of the solution. Assume water has a density of 1.00 g/cm3
