(a)
Interpretation:
The ratio of the populations of two energy states whose energies differ by 500 J at (a) 200 K and the trend is to be calculated.
Concept introduction:
From kinetic theory of gases, we know that the average kinetic energy of a ideal gas molecule is given by ½ kT for each degree of translation freedom. In this equation k is given as Boltzmann constant and T is given as absolute temperature (in K). Boltzmann effectively utilized this concept to derive a relationship as the natural logarithm of the ratio of the number of particles in two energy states is directly proportional to the negative of their energy separation. Thus, the Boltzmann distribution law is given as,
Probability = e –(ΔE/RT)
(b)
Interpretation:
The ratio of the populations of two energy states whose energies differ by 500 J at (b) 500 K and the trend is to be calculated.
