Consider the classical canonical partition function. Show that, for any system at any state, the total free energy and entropy can be written as the sum of an ideal gas part and an excess part, A(T,V,N)=AIG(T,V,N)+Aex(T,V,N) and S(T,V,N)=SIG(T,V,N)+Sex(T,V,N) Derive general expressions for these two excess quantities in terms of the configurational partition function
