B/c the textbook mentions that Einstein's heat capacity equation obeys a law of corresponding states....but, I don't really understand how this can be.....I've tried to figure out, to no avail.....so, any help would be welcome!
Cv/NkB = 3R(hv/(kBT))2e-[hv/(kBT)]/(1-e-[hv/(kBT)])2
The Attempt at a Solution
I tried to use compressibility factor, Z = PV/RT, but it doesn't work.....
Plus, I understand that the law of corresponding states = properties of ALL gases are the same if compared under same conditions relative to their critical point. So, considering it is ALL gases, the Einstein heat capacity should also work. But, how???? Is it a matter of normalization or something?
