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.   (1)ClO(g)+O3(g)⟶Cl(g)+2O2(g)Δ?∘rxn=−122.8 kJ (2)2O3(g)⟶3O2(g)Δ?∘rxn=−285.3 kJ (3)O3(g)+Cl(g)⟶ClO(g)+O2(g)   Δ?∘rxn= ?

Interpret your result from part a. Will the formation of AB2(s) occur under standard state conditions? Why or why not?

Treat your data sets independently. Enter your data in two columns in a spreadsheet. Your goal is to plot In K vs. 1/T (remember to use the absolute temperature). To determine K, you need to calculate the concentrations of all species that appear in the equilibrium expression. Do this as follows: [COC142-]: Use Beer's Law to calculate this concentration ( = 572 L mol-1 cm-1). However, you need to "adjust" your measured absorbance. Since both compounds absorb at 692 nm, not all of the light absorbed is due to the blue, chloride species. A small amount is due to the pink, aquo complex. Fortunately, this is a small amount, but it becomes important when the concentration of the chloro complex is very low. To compensate, divide the absorbance of the [Co(H2O)6]2+ at 511 nm by 29 ( this is the ratio of the molar absorptivity of this complex at 512 nm to that at 692 nm) and subtract this value from every absorbance measurement in your data set.* Use this "adjusted" absorbance to calculate the…
