Question

3. Answer the following questions about (a) The O, molecule has a central oxygen atom bonded to two outer oxygen stoms that are not bonded to one our and 45 m another. In the box below, draw the Lewis electron-dot diagram of the O, molecule, Inctude all valid resonance structures LCULATOR ions ta re ponse quest wh questio arly show redia for (b) Based on the diagram you drew in part (a), what is the shape of the ozone molecule? Ozone decomposes according to the reaction represented below (c) The bond enthalpy of the oxygen-oxygen bond in O, is 498 kJ/mol. Based on the enthalpy of the reaction repres t two 0.1 represented above, what is the average bond enthalpy, in kJ/mol, of an oxygen-oxygen bond in O, Ozone can oxidige HSO, Tag), as represented by the equation below A solution is prepared in which the initial concentration of Hsotaq) (64x í?4 M) is much larger than that of Ofaq) (1.0 × 10-5 M), The concentration of 0s(aq) is monitored as the reaction proceeds, and the data are plotted in the graph below 1.0 x 10-3, 8.0 x 10-6 60x 10- 4.0 x 10-6 2.0x 10-6 0 001 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 0.10 Time (s) GO ON TO THE NEXT PAGE or reuse of part of this page is iegal -14-
