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?
