PROBLEM 1-6 Not all XO molecules such as NO, survive long enough to react with oxygen atoms; some are photochemically decomposed to X and atomic oxygen, which then reacts with O₂ to re-form ozone. Write out the three steps (including one for ozone destruction) for this process and add them together to deduce the net reaction. Does this sequence destroy ozone overall, or is it a null cycle, which is defined as one that involves a sequence of steps with no chemical change overall?

Module 14 Discussion: Logarithmic Application A Radiative Forcing Radiative forcing, R, measures the influence of carbon dioxide in altering the additional solar ration trapped in Earth's atmosphere. The International Panel on Climate Change (IPCC) in 1990 estimated k to be 6.3 in the radiative forcing equation R = k In(), where Co is the preindustrial amount of carbon dioxide and C is the current level. (Data from Clime, W., The Economics of Global Warming, Institute for International Economics, Washington, D.C.) (a) Use the equation R = 6.3 In() to determine the radiative forcing R, in watts per square meter (W) to the nearest tenth, expected by the IPCC if the carbon dioxide level in the atmosphere doubles from its preindustrial level. (b) Determine the global temperature increase T, in degrees Fahrenheit to the nearest tenth, that the IPCC predicted would occur if atmospheric carbon dioxide levels were to double, given T(R) = 1.03R.
