Problem 14.13

Based on the following reaction profile, how many intermediates are formed in the reaction $$\mathrm{A} \longrightarrow \mathrm{C}$$? How many transition states are there? Which step, $$\mathrm{A} \longrightarrow \mathrm{B}$$ or $$\mathrm{B} \longrightarrow \mathrm{C}$$, is the faster? For the reaction $$\mathrm{A} \longrightarrow \mathrm{C}$$, is $$\Delta E$$ positive, negative, or zero? [Section 14.6]

Step-by-Step Solution:

Step 1 of 5) According to EPA regulations, utilities serving more than 50,000 people must monitor the level of lead in their water and take corrective action if more than 10% of the homes sampled exceed the 15 ppb limit. Tests performed on samples collected in September 2015 by researchers from Virginia Tech found that in 10% of the 252 Flint homes tested the lead concentration exceeded 25 ppb, and in several homes the concentration exceeded 100 ppb. At the same time, a local pediatrician analyzed the results of infant blood tests and found that the percentage of children with elevated concentrations of lead in their bloodstream (750 ppb) had doubled from 2.4% in 2013 to 4.9% in 2015. The troubles began in April 2014 when the city began using the nearby Flint River as the natural source of its municipal water. Prior to that, Flint obtained water from Detroit, where water taken from Lake Huron was treated before piping it to Flint. The source of the lead was not the Flint River itself, but corrosion from lead pipes that are present in the underground water distribution network. Why did the change in water supply dramatically increase the leaching of lead from the old pipes Many factors were at play, but basically they all came down to solubility considerations.
