2. Consider a reentry vehicle. 2.5 (a) Estimate the degree of dissociation a for 02 20 @ 10000 ft, and 50000 ft (ignore shock). (b) Estimate the degree of dissociation a for M = 5 and the near surface temperature 3000 K. (c) Estimate the degree of dissociation a for M = 10 and the near surface temperature 6000 K. Also, can you estimate the degree of ionization for O=0+ + e? Note that 0, 0+ and e can be considered as perfect gas and mass action law can be applied. The first ionization potential of O is = 13.6 eV. E = 35.1 eV.
