3. For diatomic ideal gases at room temperature, find out the change in entropy due to mixing using the following partition functions hv expl2kT T V( h2 Ztranslation rotation vibration h2 hv 1 exp 4. For solids, Einstein the vibrational levels given energy are as hv, j-0,1,2,.. Assuming that the N 2 strongly coupled atoms are +=3 equivalent to 3N simple harmonic independent oscillators, find out the followings (a) Equation for the vibrational energy as a function of temperature (b)...

The density of the quantum states is given by g(e)= "V"m3/21/2 h3 kT 1/2-/kTde TkT 2 If needed, use the following integral; 2. For monatomic ideal gas of N particles in volume V which follows the Maxwell-Boltzmann distribution, find out the speed distribution N(v)dv....
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...
