Unformatted text preview: 16.6 Transition theory 6. Draw the transition state in the following reaction: [note, it may be easier to begin with Lewis structures of each compound] H 2 + CO CH 2 O 7. For the diagram below, indicate where the reactants, the transition state and the products would be located. Also label the activation energy of the diagram and the net change in energy. 8. Does the above diagram represent an endothermic or exothermic reaction? 16.7 Reaction Mechanisms 9. For the chemical reaction: 2 HNO 2 + N 2 O 4 NO + H 2 O Is found to be second order with respect to N 2 O and zero order with respect to HNO 2 . 2 N 2 O N 2 + 2 NO ( slow ) N 2 + HNO 2 N 2 O + HNO ( fast ) HNO + HNO 2 H 2 O + 2 NO ( fast ) Does the slow step suggest a rate law that matches experimental evidence? Is this reaction mechanism plausible? Label the intermediates in this reaction mechanism. Describe how increasing the concentration of HNO 2 would effect the overall reaction rate?...
