(1) Derive the expression for [tex]\mu[/tex]PG for a monatomic molecule (like argon) which has no internal structure and only has translational energy. where [tex]\mu[/tex]PG is the perect gas contribution to the chemical potential. (2)Treating the molecule N2 as a linear, rigid molecule is an excellent approximation. Calculate numerical values of the perfect gas contribution to the molar entropy and the molar isobaric heat capacity for N2 at 0 oC and 1 atmosphere. Justify any contributions to the internal energy of the molecule that you omit from your calculation. For this i can plug the numbers in, i am just unsure of the equations to use.
