Problem 1 22 A Certain Stellar Atmosphere With A Pressure 1 000 Dynes Cm Consists Entirely Of Hydrogen By Ignoring St 1 (53.62 KiB) Viewed 18 times

Problem 1-22: A certain stellar atmosphere with a pressure 1,000 dynes/cm² consists entirely of hydrogen. By ignoring statistical weights, i.e., setting the ratio of partition functions equal to 1, find the temperature at which the H, molecules are 50 percent dissociated. The binding energy of the H, molecule is 4.48 ev. (The problem here is that the dissociated par- ticles have comparable mass. How will that fact modify the ionization equation?)
