CHEM 302 Organic Chemistry I Problem Set VIII Chapter 8 Introduction : The usual. Just a short little one to give you a bit of a review of Chemistry II. 1) The bond energies for Cl-Cl, H-Cl, and CH 3 -H are 58, 103, and 104 kcal/mol, respectively. Draw an energy diagram depicting the following reaction sequence: Cl Cl Cl + Cl Cl + CH 4 H Cl + CH 3 2) Calculate the Δ H for the reaction given in problem 1. Is this reaction exothermic or endothermic? 3) The reaction shown below is a reversible process, with K close to unity. CH 3 CH 2 OH + (CH 3 ) 2 CH C OH O (CH 3 ) 2 CH C OCH 2 CH 3 O + H 2 O a) Assuming that K = 1 and that the concentration of each starting material is 0.5

Unformatted text preview: M , what are the concentrations of all the species after the reaction has reached equilibrium? b) Suggest two ways of increasing the yield of the product ester ( A ) 4) The combustion of hydrogen (yielding H 2 O), ethylene (yielding CO 2 and H 2 O) and ethane (yielding CO 2 and H 2 O) is characterized by the following Δ H values: -68.4 kcal/mol, -337.0 kcal/mol, and -372.8 kcal/mol, respectively. Is this information enough to calculate the Δ H° for the hydrogenation (addition of H 2 ) of ethylene to give ethane? If so, calculate the Δ H for this reaction....
