The 1995 Nobel Prize in Chemistry was shared by Paul Crutzen, F. Sherwood Rowland, and Mario Molina for their work concerning the formation and decomposition of ozone in the stratosphere. Rowland and Molina hypothesized that chlorofluorocarbons (CFCs) in the stratosphere break down upon exposure to UV radiation, producing chlorine atoms. Chlorine was previously identified as a catalyst in the breakdown of ozone into oxygen gas. Using the enthalpy of reaction for two reactions with ozone, determine the enthalpy of reaction for the reaction of chlorine with ozone.

In a hot combustion chamber, oxygen diffuses through air to a flat carbon surface where it reacts to produce CO and/or CO2. Reduce the general differential equation for mass transfer to write a specific differential equation for oxygen that will describe the steady-state mass transfer process. The concentration of oxygen at z=δ is 21 mole percent. The reaction at the surface may be assumed to occur instantaneously. No reaction occurs in the gas film. What would be the form of the equation providing the flux of oxygen if (a) only carbon monoxide is produced on the carbon surface; (b) only carbon dioxide is produced on the carbon surface; (c) the following instantaneous reaction occurs on the surface, 4C+3O2→2CO+2CO2.
