# Question

Using data from Appendix 4, calculate ΔHo, ΔGo, and K (at 298 K) for the production of ozone from oxygen:
3O2(g) ⇌ 2O3(g)
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 × 1023 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.
