1. Using the given energy diagram, label the activation energy (Ea) for each step and the enthalpy change for the overall reaction (Af,Then, identify each of the following: Reactants Transition State(s) Intermediate Rate-limiting Step The overall reaction is: a) Exothermic b) Endothermic 2. Rank the free radicals (I-III) shown below in order of decreasing stability (i.e., from most stable to least stable (CH3)3C, CH2-CHCH2, CH3CH2, CH3-, (CH3)2CH 3. Which H atom in the molecule shown will be most readily abstracted by a bromine radical? Explain your answer to get credit.Explanation / Answer
Q1
a ---> this must be the reactants, since it is the beggining of the reaction
b --> this must be the rate-limiting step (as well as a transition step), since the activation energy (a to b) is the highest, therefore, reuqires much more time than all other steps, which implies this is the rate-limiting step
c ---> these are intermediates; which will not be present in the end
d --> this is a transition state
e --> these are products, which are at the end of the reaction coordinate.
According to the relative value in the y-axis with respec tto a and e
e > a
then
this is endothermic, it absorbe energy
