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, 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) specific heat at constant volume.
