5. Consider a quantum mechanical system made of N identical particles. There are total M possible energy levels that each of these particles can occupy. (a) According to statistical thermodynamics, the probability that a particle occu- pies ith energy level with energy e; is proportional to e-Bes where B = r and T is the temperature. k is a universal constant called Boltzmann constant. What is the probability for a given particle to occupyith energy level? (b) On average, how...

8. (10 pts) (a) (6 pts) Suppose a system consists of N noninteracting, indistin guishable, identical particles and that each particle has available to it only two quantum electronic states, whose energies are 0 and a. Find expressions for z, Z and U. Note: Because we don 't consider translational energy here, so the 1/N! should be om itted when writing Z in terms of z (b) (4 pts) For NO, the ground electronic level and the first exited electronic...
