Name: Chemistry 008, Spring 2008 Cornell University Dr. Pontrello Due 4/13/08 Learning Strategy Questions #9 Any time you write down a number, please include correct units when applicable. Clearly write any equation(s) that you are using to answer each question, and also clearly indicate the steps used to answer the questions, if appropriate. Part I: Calculating Δ G rxn from Entropy and Enthalpy. I.1 (10 points) For the following reaction at 25 o C, NH 3 (g) + HNO 3 (aq) NH 4 NO 3 (aq) use the Data Tables in Appendix D of your textbook to calculate a) Δ H rxn o b) Δ S rxn o I.2 (7 points) Based on your calculations above, what is the value for

Unformatted text preview: G rxn o ? Would you predict the reaction to be product or reactant favored at equilibrium? Is the reaction driven by entropy or enthalpy? Name: 2 Part II: Calculating G rxn from G f . II.1 (12 points) For the following reaction at 25 o C, use the Data Tables in Appendix D of your textbook to calculate G rxn o . Based on your calculations, do the reactions favor products (spontaneous) or reactants (non-spontaneous)? (Be sure the reactions are balanced.) a) K (s) + Cl 2 (g) KCl (s) b) CuO (s) Cu (s) + O 2 (g) c) NH 3 (g) + O 2 (g) NO 2 (g) + H 2 O (g)...
