Answer Q39, 40, 41
Dinitrogen trioxide, N2O3, is largely dissociated into NO and NO2 in the gas phase where there exists the equilibrium, N2O3 = NO + NO2 In an effort to determine the structure of N2O3, a mixture of NO and "NO2 was prepared containing isotopically labeled N in the NO2. After a period of time the mixture was analyzed and found to contain substantial amounts of both *NO and *NO2. Explain how this is consistent with the structure of N2O3 being ÔNONO. Because this is an equilibrium process, there is a change that either the forward or the reverse reactions will occur. As NO reacts with NO2 we form This compound can decompose and give either NO2 and and "NO2. or After sufficient time, v will be present in the mixture. both "NO and NO Attempts: 0 of 3 used Submit Answer Save for Later only *NO only NO

2) Suppose that we have 100 cm' of water (p = 1g.cm"), which is D;0 in a proportion of %3! 0.015% (D stands for deuterium, or H). a) Compute the energy (in J) that would obtain from this sample if all the deuterium were to be consumed in the reaction H + H - 'H+p, which is known to release an energy output of 4.0 MeV. b) As an alternative, compute the energy (in J) that would be released if two-thirds of the deuterium were fused (according to the previous reaction) to form 'H, which then combines with the remaining one third according to the reaction H+ 'H → *He +n, known to release an energy output of 17.6 MeV. c) Which of the processes a) or b) produces more energy?

When a CFC is broken down, the chlorine generated is a free radical, which has an unpaired electron and is highly reactive. It is sometimes shown as -CI. This chlorine can react with ozone by the following reaction CI + 03 + CIO + 02 The CIO is also highly reactive and can itself react with an oxygen free radical in the atmosphere: -0 + CIO > -CI + 02 After these two reactions occur, a chlorine-free radical is regenerated. What can it then do in the atmosphere? Why are chlorofluorocarbons so damaging because of this?
