Unformatted text preview: (aka EPR) spectrum? (b) Explain - briefly. 8^8 is the orbital depiction of the SOMO for the allyl radical, 4. 4. Formulate a qualitatively accurate diagram, free energy on the y-axis and reaction progress on the x-axis, which illustrates a process wherein a kinetically preferred product is also the thermodynamically preferred product. 5. The Arrhenius function for the rather strange looking transformation shown below is 12.7 - 13.8/e. xnt \/ (a) \A/hat is the activation energy for the transformation? (b) What is the value of "log A"? (c) Formulate a mechanism to account for the transformation. 6. Consider a hypothetical equilibrium process (see below), conducted at 25 'C (298 K). Suppose that the difference in free energy between A and B is 2.8 kcal/mol, and that structure B is the more stable. \A/hat will be the equilibrium ratio of B to A?
