Webtackle the partition function for one molecule, denoted 1. Since the total energy of a molecular system is the sum of translation ( trans), vibrational ( vib), rotational ( rot), and electronic ( el) components, we can say that the molecular partition function is the product of all its individual components, such that WebGbeing the Gibbs free energy. We now extend this to the semi-grand partition function and obtain the following important relation which shows that the semi-grand partition function defines the chemical potential of the fixed component, k BTln˜=−k BTlnQ+ > 1 N ˆμ ˆ=−A+G−N 1μ 1 = PV −N 1μ 1.
