(Q2) (20 pts) Derivation of Saha Equation Consider a system consisting of Hydrogen ions H+ and the Hydrogen atoms. Hence, for a single atom, there exist two possible states: occupied by an electron (H) and unoccupied (p). Assume the ionization energy to be I. Calculate the ratio of probabilities P, and PH of these two states in order to obtain the Saha equation: P₂ KT e-1/KT PH PvQ where P, is the pressure of the electron gas and uo is the quantum volume. = Hint-1: Treat the electron gas as an ideal gas: PV = NKT. Hint-2: Neglect the electron spins and take the chemical potential to be: V NUQ μ=-kT In-
