Chapter 17, Problem 105CP

Using data from Appendix 4, calculate ∆H°, ∆G°, and K (at 298 K) for the production of ozone from oxygen:

$3{\text{O}}_{\text{2}}\left(g\right)\rightleftharpoons 2{\text{O}}_{\text{3}}\left(g\right)$

At 30 km above the surface of the earth, the temperature is about 230. K and the partial pressure of oxygen is about 1.0 × 10⁻³ atm. Estimate the partial pressure of ozone in equilibrium with oxygen at 30 km above the earth's surface. Is it reasonable to assume that the equilibrium between oxygen and ozone is maintained under these conditions? Explain.
