(10 pts) Deuterium is often used as a label in organic chemistry to elucidate the mechanisms of organic reactions. Because Deuterium has 2 times the mass of Hydrogen, breaking a C-D generally leads to an increase in the activation energy ($E_a$) for that transition state. This is known as a kinetic isotope effect. In the following reaction scheme it is shown that treatment of the tosylate with sodium ethoxide leads to a mixture of alkenes in a 98: 2 ratio. Conversely, when the tosylate is heated in acetic acid a 1:1 mixture of the alkenes is formed. Please explain this result.
