One kilo mole of argon gas at room temperature is heated to 20000 K, 100 kPa.
Assume that the plasma in this condition consists of an equilibrium mixture of Ar,
Ar`, Ar``, and e according to the simultaneous reactions
1) Ar Ar+ + e– 2) Ar+ Ar++ + e– The ionization equilibrium constants for these reactions at 20000 K have been calculated from spectroscopic data as ln K1 = 3.11 and ln K2 = -4.92. Determine the equilibrium composition of the plasma.
