7. At room temperature cyclopentadiene reacts with itself to form dicyclopentadiene in a Diels-Alder reaction. a) draw the self reaction of cyclopentadiene at 20°C. b) When dicyclopentadiene is heated to boiling (170°C), the retor-Diels-Alder reaction occurs producing 2 moles of cyclopentadiene. Explain this observation in terms of free energy, enthalpy and entropy. c) If the AHpxn = -75 kJ/mol and the ASpxn = -226 J/mol K, What temperature would be required for the reaction to be at equilibrium (Keq = 1).
