Gaseous ozone undergoes decomposition according to the stochiometric equation: 203 (g) 302 (g) Two alternative mechanisms have been proposed to account for this reaction. 203 302 bimolecular, rate constant k Mechanism I Mechanism II 0302+0 fast equilibrium, equilibrium constant K 0+ 03 202 slow, rate constant k2 A. Derive rate laws for the formation of O for each mechanism. B. Thermodynamic measurements give standard enthalpies of formation for each of the following species at 298 K: species O (g) 03 (g) O(g) 298 (kJ/mol) 0.0 142.3 249.4 The observed activation enthalpy AHF for the overall reaction 203-302 is 125.5 kJ/mol of O3. Sketch a curve of enthalpy per mol O3 versus reaction coordinate for each of the proposed mechanisms. Label the curves with numerical values for the AH between reactants, products, intermediates, and transition states. (Tinoco #33, p.375) Upload your answers to parts A and B as a file.
